Chuck Zhang, GTMI faculty member and the Harold E. Smalley Professor in the H. Milton Stewart School of Industrial and Systems Engineering, is one of five faculty members will help grow the College of Engineering’s work in high-impact cyber-physical systems security (CPSS) as new Cybersecurity Fellows.

Fellows represent expertise in a variety of areas of CPSS, which addresses risks where cyber and physical worlds intersect. That includes the Internet of Things (IoT), industrial systems, smart grids, medical devices, autonomous vehicles, robotics, and more.

“As devices, systems, and the world continue to become more connected, cyber-related threats that were traditionally limited to the digital domain have made their way to physical systems,” said Raheem Beyah, dean of the College, Southern Company Chair, and a cybersecurity expert. “The College of Engineering has world-renowned cybersecurity and artificial intelligence researchers. This new cohort will continue to expand the College’s breadth of expertise and leadership in CPSS.”

The three-year fellowship was made possible by a gift from Kyle Seymour, a 1982 mechanical engineering graduate who retired as president and CEO of S&C Electric Company in 2020. Seymour wanted to help increase cybersecurity-related research and instruction within the College.

School chairs nominated potential fellows, who were evaluated and selected by a committee of senior cybersecurity researchers and College leaders.

Centipedes are known for their wiggly walk. With tens to hundreds of legs, they can traverse any terrain without stopping.

“When you see a scurrying centipede, you're basically seeing an animal that inhabits a world that is very different than our world of movement,” said Daniel Goldman, the Dunn Family Professor in the School of Physics. “Our movement is largely dominated by inertia. If I swing my leg, I land on my foot and I move forward. But in the world of centipedes, if they stop wiggling their body parts and limbs, they basically stop moving instantly.”

Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians at the Georgia Institute of Technology are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.

These robots can move over complex, bumpy terrain — and there is potential to use them for agriculture, space exploration, and even search and rescue.

The researchers presented their work in the papers, “Multilegged Matter Transport: A Framework for Locomotion on Noisy Landscapes,” in Science in May and “Self-Propulsion via Slipping: Frictional Swimming in Multilegged Locomotors,” in Proceedings of the National Academy of Sciences in March.

A Leg Up

For the Science paper, the researchers were motivated by mathematician Claude Shannon’s communication theory, which demonstrates how to reliably transmit signals over distance, to understand why a multilegged robot was so successful at locomotion. The theory of communication suggests that one way to ensure a message gets from point A to point B on a noisy line isn’t to send it as an analog signal, but to break it into discrete digital units and repeat these units with an appropriate code.

“We were inspired by this theory, and we tried to see if redundancy could be helpful in matter transportation,” said Baxi Chong, a physics postdoctoral researcher. “So, we started this project to see what would happen if we had more legs on the robot: four, six, eight legs, and even 16 legs.”

A team led by Chong, including School of Mathematics postdoctoral fellow Daniel Irvine and Professor Greg Blekherman, developed a theory that proposes that adding leg pairs to the robot increases its ability to move robustly over challenging surfaces — a concept they call spatial redundancy. This redundancy makes the robot’s legs successful on their own without the need for sensors to interpret the environment. If one leg falters, the abundance of legs keeps it moving regardless. In effect, the robot becomes a reliable system to transport itself and even a load from A to B on difficult or “noisy” landscapes. The concept is comparable to how punctuality can be guaranteed on wheeled transport if the track or rail is smooth enough but without having to engineer the environment to create this punctuality.

“With an advanced bipedal robot, many sensors are typically required to control it in real time,” Chong said. “But in applications such as search and rescue, exploring Mars, or even micro robots, there is a need to drive a robot with limited sensing. There are many reasons for such sensor-free initiative. The sensors can be expensive and fragile, or the environments can change so fast that it doesn’t allow enough sensor-controller response time.”

To test this, Juntao He, a Ph.D. student in robotics, conducted a series of experiments where he and Daniel Soto, a master’s graduate in the George W. Woodruff School of Mechanical Engineering, built terrains to mimic an inconsistent natural environment. He then tested the robot by increasing its number of legs by two each time, starting with six and eventually expanding to 16. As the leg count increased, the robot could more agilely move across the terrain, even without sensors, as the theory predicted. Eventually, they tested the robot outdoors on real terrain, where it was able to traverse in a variety of environments.

“It's truly impressive to witness the multilegged robot's proficiency in navigating both lab-based terrains and outdoor environments,” Juntao said. “While bipedal and quadrupedal robots heavily rely on sensors to traverse complex terrain, our multilegged robot utilizes leg redundancy and can accomplish similar tasks with open-loop control.”

Next Steps

The researchers are already applying their discoveries to farming. Goldman has co-founded a company that aspires to use these robots to weed farmland where weedkillers are ineffective.

“They’re kind of like a Roomba but outside for complex ground,” Goldman said. “A Roomba works because it has wheels that function well on flat ground. Until the development of our framework, we couldn’t confidently predict locomotor reliability on bumpy, rocky, debris-ridden terrain. We now have the beginnings of such a scheme, which could be used to ensure that our robots traverse a crop field in a certain amount of time.”

The researchers also want to refine the robot. They know why the centipede robot framework is functional, but now they’re determining the optimal number of legs to achieve motion without sensing in a way that is cost-effective yet still retains the benefits.

“In this paper, we asked, ‘How do you predict the minimum number of legs to achieve such tasks?’” Chong said. “Currently we only prove that the minimum number exists, but we don't know that exact number of legs needed. Further, we need to better understand the tradeoff between energy, speed, power, and robustness in such a complex system.”

Lisa Marks is launching the ancient craft of fishing villages into space vehicle design. Her work adapting traditional textile handcraft to modern problems created a unique opportunity for collaboration cleaning up space debris.

According to NASA's Orbital Debris Program Office (OPDO), this debris jeopardizes future space projects. Large objects like rocket bodies and non-functional satellites are the source of fragmentation debris.

The OPDO website says removal of even five of the highest-risk objects per year could stabilize the low Earth orbit debris environment.

A research team with members from the Georgia Tech Research Institute, the Aerospace Systems Design Laboratory, and the Space Systems Design Laboratory has developed a concept using a net to capture and de-orbit large debris.

A mutual connection at Tech's GVU recommended that the team speak to Lisa Marks, assistant professor in the School of Industrial Design, based on her work combining traditional textile with new materials and methods.

Putting Textiles in Space Requires Creative Expertise

“There’s a lot of different projects on space debris happening all around the world,” Marks said, “and there’ve been a few concept papers talking about using a net.”

“But all the drawings of the net are basic concepts, just a square with a few hatches through it. No one has figured out what that net might be.”

Marks researches ways to combine traditional textile handcraft with algorithmic modeling. “I specialize in analyzing the shape of every stitch and how we can use that stitch differently. Can we create new patterns through coding, or make it larger and out of wood?”

“It allows me to think really creatively about how we can use different textiles.”

This innovative, exploratory approach is a natural fit to create a net for a job no has ever done. “There's a lot of technical considerations with this,” Marks said. 

“It must pack incredibly small, weigh very little, and still be strong enough to capture and drag a rocket fuselage. There are considerations just for a material to exist in space. It needs to have low UV reactivity, low off gassing.”

“We need to understand every single little aspect of each of these techniques in order to do this.”

Static Nets Catch Fish; Slippery Nets Catch Rockets

Marks is working with Teflon, using the same knots used for fishing nets, but the non-traditional material means the nets work differently than fishing nets, she said. “These knots are made to be static, because you don’t want fish to get through the nets. But because Teflon is so slippery, the knots move around.”

“I think it will help the net’s strength, because the net will deform around irregular shapes before it breaks. What makes it unsuitable for fishing and annoying to work with becomes a huge benefit for what we need it to do.”

Some traditional handcraft techniques are dying out, and Marks sees projects like this as a reason preserving these techniques is important. “We don’t know what problems we’re going to have to solve in the future, and these crafts can be used in really surprising ways.”

“I would not have thought, ‘Netted filet lace, that’s how we’re going to solve a space problem!’ But if we lose this type of lace, we can’t solve space problems with it.”

Georgia Institute of Technology’s Center for Education Integrating Science, Mathematics, and Computing (CEISMC) is at the center of a new statewide initiative combining artificial intelligence and manufacturing innovations with transformational workforce development and K-12 outreach. The Georgia Artificial Intelligence Manufacturing Corridor project (Georgia AIM) is supported by a record-shattering $65 million grant Georgia Tech received in September 2022 from the U.S. Department of Commerce’s Economic Development Administration.

Georgia AIM will support a total of nine inter-related projects throughout the state and is designed to increase job and wage opportunities in distressed and rural communities and among historically underrepresented and underserved people. Georgia AIM targets rural residents, women, Black, Indigenous and People of Color (BIPOC), those living with disabilities, and veterans — groups historically underrepresented in manufacturing. Through innovation, collaboration, education, and participation, Georgia AIM will provide the tools and knowledge to empower these communities to participate fully in a diverse AI manufacturing workforce.

“Many people have preconceived notions about manufacturing and may not be able to see how they could possibly connect to it," said Roxanne Moore, Woodruff School of Mechanical Engineering’s senior research engineer and director of CEISMC’s K-12 InVenture Prize program. “What they may not realize is that manufacturing is what brings new ideas to life. AI is rapidly reshaping the manufacturing industry and changing the landscape for job opportunities. The work that we are doing will position Georgia to lead the nation into the future of AI and manufacturing.”

Moore explains that through Georgia AIM, CEISMC will expand its K-12 InVenture Prize invention and entrepreneurship program to collaborate with school districts and businesses in Southwest Georgia, Southeast Georgia and Northeast Georgia. The initiative will expand on existing partnerships Georgia Tech has established with technical colleges and minority-serving institutions.

The project will reach at least 1,000 K-12 students and 100 teachers from underserved areas, with a focus on rural communities via existing programs at Georgia Tech, other nonprofits, the Technical College System of Georgia, the Southwest Georgia Regional Commission, local manufacturers, and K-12 school leaders, Moore said.

“We need to illustrate the powerful relationships between innovation, entrepreneurship, and manufacturing so that students can see how ideas come to life and how they can improve their communities,” said Moore. “It is my hope that these regional ecosystems become a role model for how educational institutions can support each other in expanding access to high-quality STEM experiences for diverse students who typically are not empowered to create their futures.”

As part of Georgia AIM, CEISMC will also expand its offerings through partnerships with the institute’s GoSTEM program to better serve Latino populations. GoSTEM is a collaborative partnership at Georgia Tech between CEISMC and Institute Diversity, Equity and Inclusion (IDEI). Its mission is to promote STEM academic achievement and college attendance among Latino and other cultural and linguistic minority K-12 students. Plans include translating existing invention and entrepreneurship curriculum into Spanish, adding lessons to the curriculum on AI and manufacturing, assisting with the development of regionally focused curricula, and expanding training and events to make them more inclusive.

“Our goal is to make invention education accessible to everyone in the state, especially those who may have been previously left out of the conversation,” said Danyelle Larkin, educational outreach manager with CEISMC. “By going into more rural areas of the state and working to develop multi-lingual curricula that is focused on the needs of the region, we hope to serve as a national model for how to accelerate the transition to automation in manufacturing while diversifying the next generation of AI leadership.

Additional Georgia AIM expansion plans for CEISMC and K-12 InVenture Prize include supporting an existing high school entrepreneurship program in Fitzgerald and working with Albany State University to host teacher workshops, support local schools, and host regional competitions with a focus on inventiveness and the entrepreneurial mindset.

"The overall goal of Georgia AIM is to establish the United States as a leader in AI manufacturing while making sure that these systems complement rather than replace existing workers,” Larkin said. “The work that we are doing in CEISMC plays an integral role in Georgia AIM with our specific expertise in weaving invention education and entrepreneurship into K-12 classrooms and connecting with diverse communities. This huge grant gives us a chance to amplify our work and bring even more people into the AI conversation. It’s about building a better, more equitable future for the people of Georgia.”

Women make up just 24% of the automotive industry, but Georgia Tech graduates Jenn Voelker and Julia Vorpahl haven't let statistics stop them from paving their own way in a male-dominated field.

Both Voelker and Vorpahl work for Karma Automotive, a luxury electric vehicle manufacturer based in California. Beginning with their time at Tech, they've never let gender bias stop them from pursuing their passion.

"It's math," Vorpahl, a visualization and digital design modeler at Karma, said. "You either get the question right, or you get the question wrong. I think that attitude really helps when you get into a professional environment. It teaches you to have tougher skin where if you are the best for that job, you will get the job. That's what Georgia Tech instilled."

Vorpahl grew up in the industry watching her family operate what is now the oldest independently owned Mercedes-Benz dealer in metro Atlanta after her grandfather, an engine designer for the German automaker, came to America and opened the shop in 1967. She arrived at Georgia Tech unsure if she'd follow in her family's footsteps, but ultimately, she landed an internship at Daimler, the nation's largest commercial vehicle manufacturer.

While other interns came in with a background in automotive design, Vorpahl’s willingness to learn and tireless work ethic landed her a full-time job as the only woman in the company's design studio.

During her three years at Daimler before accepting her position at Karma in 2022, she'd occasionally make the drive from Portland, Oregon, back to Georgia. Along the way, she crossed paths with truckers, who often expressed surprise that Vorpahl was among those behind the scenes designing their rigs. She often heard questions like “Why do you work there?” or “How did you end up there?”

And her response was simple. "Women like cars, too.” 

That rang true through Voelker's childhood as well. When the senior director of program management for Karma arrived in Atlanta for her first year at Georgia Tech, she knew she'd found a place that could help her turn an aptitude for math and science, and a fervor for cars, into a career.

"Best move I ever made," Voelker said on her decision to enroll at Tech, although it wasn't just the Institute's stellar reputation that lured her from her home state of New Hampshire. "I visited campus in February. There was 6 feet of snow on the ground and then I came to Atlanta, and the flowers were blooming."

After changing her major from mechanical engineering to industrial design, Voelker got her foot in the door through an internship with Masterack, a commercial cargo vehicle equipment manufacturer based in Atlanta. She attended Tech at a time when women made up around 27% of the undergraduate population, so when she entered the workforce, she wasn't fazed. "It never bothered me. I have always felt like I fit right in, especially when it's the right school, the right class, or the right company where everybody appreciates learning from each other and working together towards a common goal," she said.

In fact, her experience on North Avenue taught her to always keep learning and never give up, a piece of advice she now passes along to other women entering the industry.

"Don’t be afraid to give your opinion in meetings, speak up and use all of the knowledge that you've learned over the years toward whatever project you're working on," said Voelker, who worked her way up the ladder at Masterack for 18 years before seeking a new challenge at Karma. “That's one thing that I haven't backed down on. If I have a strong opinion about something, I have no fear of saying it.”

Vorpahl and Voelker each commended Karma for their dedication to promoting hard-working women and a culture that fosters diversity — a principle that Vorpahl especially values after completing two study abroad programs at the University of Singapore and the University of Strathclyde.

“One of the biggest advantages was seeing how people from different countries approach design and how different schools approach design. You don’t want a bunch of people who all think exactly the same way. Otherwise, we’d all be driving around in the exact same vehicle,” she said.

Leading Karma’s commercial vehicle product line, Voelker noted that she has continued to see more women in leadership positions and at industry conferences, and she hopes that momentum carries over to the next generation. Highlighting the importance of igniting both young girls’ and boys' interest in STEM, Voelker recently spoke to a local second grade class to share her experiences.

"I've been really fortunate to have had some great mentors over my career, so I love to pay it forward to the younger generation," she said. "They were so excited, and I hope that stays with them and excites them to learn more about engineering."

In addition to providing an example to young women of how to succeed in a competitive industry, Vorpahl also hopes to share the technical aspects of what she's learned in the field with her alma mater and offer future graduates a roadmap to a career in automotive design.

"The students would thrive in this industry because it is so nitpicky, and Tech minds would just love it," she said. "There's not really a direct path from the Georgia Tech studios into car studios, so I'm hoping that I can show them that path."

Voelker and Vorpahl are bonded by their employer and their alma mater, but it’s their shared passion for seeing their hard work hit the pavement that continues to drive them.  

Idling at a crossroads no longer, the automotive industry is embracing electrification like never before. With more electric vehicles purchased in 2022 than any year prior, consumers are beginning to follow their lead. Yet, while opportunity abounds, new challenges will require an innovative approach to ensure a sustainable and accessible electric future for all.

With historic investments from major players in the EV space, including Rivian, Kia, and Hyundai, the state of Georgia is uniquely positioned to serve as a leader in this effort. As the state's leading research institute, Georgia Tech is on the cutting edge of the movement. 

The transportation sector is the largest greenhouse gas emitter in the U.S. at nearly 30%, with passenger vehicles accounting for around 80% of the sector's total output1 as of 2019. Electric vehicles are widely regarded as a budding solution to reduce emissions, but even as both demand and production continue to increase, EVs currently account for around 1% of the cars on America's roadways. 

From the supply chain to the infrastructure needed to support alternative-fuel vehicles alongside consumer hesitancy, achieving the goals set by both the public and private sectors — including the Biden Administration's target of EVs making up at least 50% of new car sales by 2030 — will not be easy. Through research and development, policy, and collaboration, Tech experts are working toward finding solutions that will serve as catalysts during this transitionary period for the environment and the way Americans drive.

This news release first appeared in the University of Arkansas Division of Agriculture newsroom, and has been tailored for Georgia Tech readers.

Researchers at Georgia Tech, the University of Arkansas System, the University of Nebraska-Lincoln, and Fort Valley State University in Georgia were awarded a $5 million grant to increase use of artificial intelligence and robotics in chicken processing to reduce waste in deboning and detect pathogens.

The grant from the U.S. Department of Agriculture’s National Institute of Food and Agriculture will establish the Center for Scalable and Intelligent Automation in Poultry Processing. The center, led by the University of Arkansas System Division of Agriculture, will join researchers from five institutions in three states in efforts to adapt robotic automation to chicken meat processing.

Douglas Britton, manager of the Agricultural Technology Research Program at the Georgia Tech Research Institute (GTRI), said his team was very excited to work on this project with experts at the four other institutions.

“The ultimate goal is to drive transformational innovation into the poultry and meat processing industry through automation, robotics, AI, and VR technologies,” Britton said. “Building on years of work in the GTRI Agricultural Technology Research Program, we are pleased to see that the USDA-NIFA has chosen this team to continue these efforts.”

Georgia Tech is a major partner in the project, and was awarded $2 million to focus on automating the processing lines that turn chickens into meat, said Jeyam Subbiah, professor and head of the food science department for the Division of Agriculture and the Dale Bumpers College of Agricultural, Food and Life Sciences at the University of Arkansas, and director of the project. The grant is for four years.

The Arkansas Agricultural Experiment Station, the research arm of the Division of Agriculture, will receive $2.2 million from the grant primarily to focus on food safety automation for poultry processing plants.

The remaining grant money will be divided between Julia McQuillan, Willa Cather professor of sociology at the University of Nebraska-Lincoln, and Brou Kuoakou, associate dean for research at Fort Valley State University in Georgia.

Jeff Buhr, a USDA Agricultural Research Service scientist, will contribute his expertise in broiler physiology to guide robotic deboning of meat, Subbiah said.

Georgia is the nation’s top broiler producer. Arkansas is number 3, according to 2021 figures from USDA.

Meeting the challenge

The recent impetus to automate chicken processing began with the Covid-19 pandemic, Subbiah said. The illness spread quickly among workers on the processing line. Since the worst of the pandemic, the poultry industry, like many others, has been having trouble hiring enough workers.

“Poultry processing lines began 70 to 80 years ago,” Subbiah said. “Since then, there have been only incremental changes in technology. Today, there’s a need for transformative change.”

Humans can feel when a knife hits a bone. In contrast, existing automation in poultry processing, like deboners, wastes a lot of meat.

“Human deboners leave about 13 percent of meat on the bones,” Subbiah said. “Automated deboners leave 16 to 17 percent. On an industrial scale, that’s a significant loss in value. We will use artificial intelligence and virtual reality to improve precision and reduce wastage.”

Automation can relieve labor shortages, Subbiah said. It also allows plants to locate in rural areas with a smaller labor force but nearer poultry houses and with lower property costs.

Initially, people working remotely may help advance robotic processing. Subbiah envisions workers logging on from home with virtual-reality goggles and haptics gloves to control robots located miles away.

While working remotely, the labor force will teach artificial intelligence how to cut up chickens of varying sizes and shapes.

“Automated machines right now are programmed to debone or cut up chickens based on an average size and shape. But no chicken is that size or shape,” Subbiah said. “Robot-wielded knives cut meat poorly. The machines have to learn how to adjust to the reality of random sizes and shapes.”

Georgia Tech’s participating scientists are all part of GTRI:

• Douglas Britton, manager of the Agricultural Technology Research Program
• Colin Trevor Usher, senior research scientist and branch head of robotics systems and technology, Agricultural Technology Research Program
• Ai-Ping Hu, principal research engineer, Agricultural Technology Research Program
• Konrad Ahlin, research engineer, Intelligent Sustainable Technologies Division
• Michael Park, research engineer, Intelligent Sustainable Technologies Division
• Benjamin Joffe, research scientist, Intelligent Sustainable Technologies Division
• Shreyes Melkote, the Morris M. Bryan, Jr. Professorship in Mechanical Engineering, associate director of the Georgia Tech Manufacturing Institute and executive director of the Novelis Innovation Hub

“We are thrilled to partner with our colleagues here in the Division of Agriculture, as well as our colleagues at Georgia Tech and the other participating institutions on this exciting project,” said David Caldwell, head of the Division of Agriculture’s poultry science department and director of the Center of Excellence for Poultry Science.

“We expect the findings from these coordinated research projects will be impactful for our stakeholders in the commercial poultry industry here in Northwest Arkansas and throughout the entire industry,” Caldwell said. “This project will help keep moving technology forward in processing and food safety of poultry.”

Kan (Kevin) Wang, senior research engineer, in the Georgia Tech Manufacturing Institute (GTMI) was selected to be part of the Research Faculty Teaching Fellows Program (Fall 2023/Spring 2024). The program aims to enhance the interaction across the Institute’s teaching and research activities. It offers research faculty the opportunity to become first-time instructors, and for those who have taught in the past, the ability to turn their cutting-edge research programs into instructional programs that enhance the teaching missions in the academic units.

Wang proposed a new course, Resilience of Biomanufacturing Supply Chains, which won his placement into the program.

“This Research Faculty Teaching Fellows Program will allow me to introduce important research topics in my research area to more Industrial Systems and Engineering (ISyE) students,” said Wang. “Case studies developed in my research projects and presented in the course will show students how to apply the knowledge learned from this course in actual industrial scenarios.”

Wang is also hoping that this teaching opportunity could help him better organize his own knowledge and research ideas in this area, and lead to new ideas that may develop into new collaborations between him and ISyE faculty. These collaborations could result in new research proposals and/or peer-reviewed papers. Plus, students taking his course would be provided opportunities to join new research projects in his lab.

According to Wang, cell therapy manufacturing is a nascent industry that will have critical workforce needs in five to ten years. He wants to expose more industrial engineering students into this emerging new industry.

Ryan Lawler realized early on in her academic career that a scientist with a great idea can potentially change the world.

“But I didn’t realize the role that real estate can play in that,” said Lawler, general manager of BioSpark Labs – the collaborative, shared laboratory environment taking shape at Science Square at Georgia Tech.

Sitting adjacent to the Tech campus and formerly known as Technology Enterprise Park, Science Square is being reactivated and positioned as a life sciences research destination. The 18-acre site is abuzz with new construction, as an urban mixed-use development rises from the property.

Meanwhile, positioned literally on the ground floor of all this activity is BioSpark Labs, located in a former warehouse, fortuitously adjacent to the Global Center for Medical Innovation. It’s one of the newer best-kept secrets in the Georgia Tech research community.

BioSpark exists because the Georgia Tech Real Estate Office,  led by Associate Vice President Tony Zivalich, recognized the need of this kind of lab space. Zivalich and his team have overseen the ideation, design, and funding of the facility, partnering with Georgia Advanced Technology Ventures, as well as the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, and the core facilities of the Petit Institute for Bioengineering and Bioscience.

“We are in the middle of a growing life sciences ecosystem, part of a larger vision in biotech research,” said Lawler, who was hired on to manage the space, bringing to the job a wealth of experience as a former research scientist and lab manager with a background in molecular and synthetic biology.

Researchers’ Advocate

BioSpark was designed to be a launch pad for high-potential entrepreneurs. It provides a fully equipped and professionally operated wet lab, in addition to a clean room, meeting and office space, to its current roster of clients, five life sciences and biotech startup, a number certain to increase – because BioSpark is undergoing a dramatic expansion that will include 11 more labs (shared and private space), an autoclave room, equipment and storage rooms.

“We want to provide the necessary services and support that an early-stage company needs to begin lab operations on day one,” said Lawler, who has put together a facility with $1.7 million in lab equipment. “I understand our clients’ perspective, I understand researchers and their experiments, and their needs, because I have first-hand proficiency in that world. So, I can advocate on their behalf.”

CO2 incubators, a spectrophotometer, a biosafety cabinet, a fume hood, a -80° freezer, an inverted microscope, and the autoclave are among the wide range of apparatus. Plus, a virtual treasure trove of equipment is available to BioSpark clients off-site through the Core Facilities of the Petit Institute for Bioengineering and Bioscience on the Georgia Tech campus.

“One of the unique things about us is, we’re agnostic,” Lawler said. “That is, our startups can come from anywhere. We have companies that have grown out of labs at Georgia State, Alabama State, Emory, and Georgia Tech. And we have interest from entrepreneurs from San Diego, who are considering relocating people from mature biotech markets to our space.”

Ground Floor Companies

Marvin Whiteley wants to help humans win the war against bacteria, and he has a plan, something he’s been cooking up for about 10 years, which has now manifested in his start-up company, SynthBiome, one of the five startups based at BioSpark Labs.

“We can discover a lot of antibiotics in the lab but translating them into the clinic has been a major challenge – antibiotic resistance is the main reason,” said Whiteley, professor in the School of Biological Sciences at Georgia Tech. “Something might work in a test tube easily enough and it might work in a mouse. But the thing is, bacteria know that mice are different - and and so bacteria act differently in mice than in humans.”

SynthBiome was built to help accelerate drug discovery. With that goal in mind, Whiteley and has team set out to develop a better, more effective preclinical model. “We basically learned to let the bacteria tell us what it’s like to be in a human,” Whiteley said. “So, we created a human environment in a test tube.”

Whiteley has said a desire to help people is foundational to his research. He wants to change how successful therapies are made. The same can be said for Dr. Pooja Tiwari, who launched her company, Arnav Biotech, to develop mRNA-based therapeutics and vaccines. Arnav Biotech also serves as a contract researcher and manufacturer, helping other researchers and companies interested in exploring mRNA in their work.

“There are only a handful of people who have deep knowledge of working in mRNA research, and this limits the access to it” said Tiwari, a former postdoctoral researcher at Georgia Tech and Emory. “We’d like to democratize access to mRNA-based therapeutics and vaccines by developing accessible and cost-effective mRNA therapeutics for global needs”.

Arnav – which has RNA right there in the name – in Sanskrit means ‘ocean.’ An ocean has no discernible borders, and Tiwari is working to build a biotech company that eliminates borders in equitable access to mRNA-based therapeutics and vaccines.

With this mission in mind, Arnav is developing mRNA-based, broad-spectrum antivirals as well as vaccines against pandemic potential viruses before the next pandemic hits. Arnav has recently entered in a collaboration with Sartorius BIA Separations, a company based on Slovenia, to advance their mRNA pipeline. While building its own mRNA therapeutics pipeline, Arnav is also helping other scientists explore mRNA as an alternative therapeutic and vaccine platform through its contract services. 

“I think of the vaccine scientist who makes his medicine using proteins, but would like to explore the mRNA option,” Tiwari posits. “Maybe he doesn’t want to make the full jump into it. That’s where we come in, helping to drive interest in this field and help that scientist compare his traditional vaccines to see what mRNA vaccines looks like.”

She has all the equipment and instruments that she needs at BioSpark Labs and was one of the first start-ups to put down roots there. So far, it’s been the perfect partnership, Tiwari said, adding, “It kind of feels like BioSpark and Arnav are growing up together.”
