During the summer, Duncan Hughes, an Environmental Technology instructor at North Georgia Technical College (NGTC) introduced his students to the web application Virtual Ecological Research Assistant, better known as VERA. It allowed students to construct conceptual models and ecological systems, as well as run interactive model simulations on the brook trout, a species of freshwater fish.

Hughes and his students sought to answer questions about reproduction and food supply, as they worked to add new complexities to the VERA application from different species of trout, circumstances, to changes. According to the Encyclopedia of Life (EOL), an international effort, led by the Smithsonian Institution's National Museum of Natural History, brook trout are found in three types of aquatic environments: rivers, lakes, and marine areas and their living requirements in these environments.

“Originally when we populated the brook trout, we noticed the brown trout shared the same life history and ecological information, but we were able to find enough information from the Encyclopedia of Life to differentiate those species,” said Hughes. “I had my students run through the process of building these components through an instructional-based format by having them manipulate some of the parameters and probabilities.”

VERA was developed by the Design & Intelligence Lab at Georgia Tech in collaboration with EOL. The technology is being used by students as an assisting tool and is publicly accessible. The data being collected from their usage is part of the research conducted at the NSF AI Institute for Adult Learning and Online Education (AI-ALOE).

“Users can jump into our program and conduct ‘what if’ experiments by adjusting simulation parameters. This is our way of providing an accessible and informal learning tool,” said Ashok Goel, director and co-principal Investigator of AI-ALOE and computer science professor at Georgia Tech. “Using VERA as an assessment tool is excellent. These students are using VERA in a way we are not.”

Goel was recently joined by Georgia Tech graduate researcher Andrew Hornback, research scientist Sandeep Kakar, and staff member Daniela Estrada at NGTC to learn more about the work in VERA and challenges Hughes and his students faced while using the application.

“The main struggle is limitation with the EOL and database,” said Hughes. “There are some species that we just can’t find, and sometimes it is glitchy and doesn’t work right away, but it is not insurmountable.”

Another challenge Hughes’ students found was not being able to find what they wanted to complete certain tasks, such as stream and environmental patterns of comparative fish ecosystems.

With that being known, AI-ALOE is working to address these issues and more to build and cater to specific student and teacher needs. At this time, the Design & Intelligence Laboratory is in the process of expanding VERA in the capability of its on-demand agent-based simulation generator, which would enable users to divide components into separate habitats.

“It was very interesting to see the results because antidotally through much research we were able to set up all these relationships and let them run the model, and the results were exactly what we would have hypothesized what they would be given those perimeters,” said Hughes.

The technical college has plans to introduce VERA to another classroom this semester held by Natural Resource Management instructor, Kevin Peyton.

About NGTC

North Georgia Technical College is a residential, public, multi-campus institution of higher education serving the workforce development needs of Northeast Georgia and part of the Technical College System of Georgia.

Advancement in technology brings about plenty of benefits for everyday life, but it also provides cyber criminals and other potential adversaries with new opportunities to cause chaos for their own benefit.

As researchers begin to shape the future of artificial intelligence in manufacturing, Georgia Tech recognizes the potential risks to this technology once it is implemented on an industrial scale. That’s why Associate Professor Saman Zonouz will begin researching ways to protect the nation’s newest investment in manufacturing.

The project is part of the $65 million grant from the U.S. Department of Commerce’s Economic Development Administration to develop the Georgia AI Manufacturing (GA-AIM) Technology Corridor. While main purpose of the grant is to develop ways of integrating artificial intelligence into manufacturing, it will also help advance cybersecurity research, educational outreach, and workforce development in the subject as well.   

“When introducing new capabilities, we don’t know about its cybersecurity weaknesses and landscape,” said Zonouz. “In the IT world, the potential cybersecurity vulnerabilities and corresponding mitigation are clear, but when it comes to artificial intelligence in manufacturing, the best practices are uncertain. We don’t know what all could go wrong.”

Zonouz will work alongside other Georgia Tech researchers in the new Advanced Manufacturing Pilot Facility (AMPF) to pinpoint where those inevitable attacks will come from and how they can be repelled. Along with a team of Ph.D. students, Zonouz will create a roadmap for future researchers, educators, and industry professionals to use when detecting and responding to cyberattacks.

“As we increasingly rely on computing and artificial intelligence systems to drive innovation and competitiveness, there is a growing recognition that the security of these systems is of paramount importance if we are to realize the anticipated gains,” said Michael Bailey, Inaugural Chair of the School of Cybersecurity and Privacy (SCP). “Professor Zonouz is an expert in the security of industrial control systems and will be a vital member of the new coalition as it seeks to provide leadership in manufacturing automation.”

Before coming to Georgia Tech, Zonouz worked with the School of Electrical and Computer Engineering (ECE) and the College of Engineering on protecting and studying the cyber-physical systems of manufacturing. He worked with Raheem Beyah, Dean of the College of Engineering and ECE professor, on several research papers including two that were published at the 26th USENIX Security Symposium, and the Network and Distributed System Security Symposium.

“As Georgia Tech continues to position itself as a leader in artificial intelligence manufacturing, interdisciplinarity collaboration is not only an added benefit, it is fundamental,” said Arijit Raychowdhury, Steve W. Chaddick School Chair and Professor of ECE. “Saman’s cybersecurity expertise will play a crucial role in the overall protection and success of GA-AIM and AMPF. ECE is proud to have him representing the school on this important project.”

The research is expected to take five years, which is typical for a project of this scale. Apart from research, there will be a workforce development and educational outreach portion of the GA-AIM program. The cyber testbed developed by Zonouz, and his team will live in the 24,000 square-foot AMPF facility.

Aaron Stebner outlined an aggressive plan for artificial intelligence and manufacturing when he applied for a faculty position in 2019. In his cover letter, he promised “to establish the Georgia Institute of Technology as a world leader in additive manufacturing of solid materials (ceramics & metals) R&D, especially in the fusion of data sciences and AI to create new, world-leading technologies.”

Stebner thought it would take 10-15 years of incremental steps and funding to achieve the goal. He was wrong.

Thanks to a new $65 million grant from the U.S. Department of Commerce’s Economic Development Administration, announced by President Joe Biden, Stebner’s plan will begin to become a reality — and include the entire state of Georgia and all of its manufacturing sectors from agriculture to airplanes — two years after arriving on campus.

The largest of the nine projects within the larger Georgia AI Manufacturing (GA-AIM) technology corridor grant will allow Stebner and Georgia Tech to transform the Advanced Manufacturing Pilot Facility (AMPF) into the Artificial Intelligence Manufacturing Pilot Facility (AI-MPF). The 24,000 square-foot facility on 14th Street will more than double in size after Georgia Tech and statewide GA-AIM partners were selected as one of 21 Phase II awardees in the $1 billion Build Back Better Regional Challenge (BBB) competition, part of the Investing in America’s Communities initiative under the American Rescue Plan Act of 2021.

AMPF has been a shell waiting for a vision like Build Back Better to fill it out,” said Stebner, associate professor the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering. “Now we will transform the facility into one of the nation’s first manufacturing labs designed for autonomy with the goal of helping the state and the nation to be world AI manufacturing leaders.”

On Wednesday, April 13th 2022, the Undergraduate Research Opportunities Program (UROP) hosted the 16th annual Spring Undergraduate Research Symposium. UROP’s annual symposium is Georgia Tech’s largest undergraduate research colloquium and allows students to present their research and gain valuable skills and presentation experience. Each year the symposium also presents awards to the top poster and oral presentation from each college and honors the Outstanding Undergraduate Researcher (OUR) from each college. And with over 40 oral presentations and nearly 90 poster presentations, this year’s symposium proved to be another success for UROP and Georgia Tech.  

This year the symposium was held in Exhibition Hall and opened with an introduction and keynote address to students, faculty, and other non-presenters. Shortly after, the event moved into the poster presentations segment where undergraduate students displayed their research to judges, faculty, and other attendees. The oral presentations followed soon after and gave student researchers the opportunity to go more in-depth with their research and findings and answer any questions the judges and attendees had. To end the event, sponsoring colleges and departments recognized Outstanding Undergraduate Researchers from their respective colleges. Additionally, the symposium judges were tasked with selecting the top student researchers having exceptional poster and oral presentations. 

Any Georgia Tech undergraduate student interested in presenting their research is encouraged to apply for future symposiums and to build on research presentation skills, connect with other undergraduate researchers and faculty, and the chance to be recognized with awards by members of the Georgia Tech research community. UROP also hosts other research-related events and workshops throughout the school year to assist undergraduate students interested in research and build on their passions!

During the summer of 2021, computer science student Neil Sanghavi and computer science recent grad Ahan Shah, both from Fairfax, VA, reconnected to catch up with one another and discuss the projects they were working on. In doing so they discovered a mutual resolve to create something using innovative technology and solve a problem relating to intellectual property, specifically patents. Both Neil and Ahan had just started to get into crypto trading and realized that NFT technology had more to offer than its collectible aspect. Here the idea of PatentX was created: to use NFT technology to provide utility in an antiquated space that lacked efficiency.

“It is estimated that we have $1 trillion in unused IP in the United States currently. Additionally, it is reported that there is $25.6 billion worth of patent monetization available today. This is why we created PatentX, a blockchain-backed marketplace to facilitate intellectual property transactions. We built this to make sure the little man innovators and entrepreneurs have an outlet to monetize and connect their patents with the world. Not only that, we are creating tools for large businesses, law firms, venture capitals to manage all of their IP on the blockchain that can handle transactions in seconds.”

Neil and Ahan describe their product launch process as a great learning experience and are firm believers that there can never be too much help. They are currently supported by DXPartners and have received help from various mentors and blockchain professionals. They have been able to traverse obstacles and learn about the marketing, finance, and business aspects behind building a startup despite coming from a technical background. 

Their vision for PatentX is to disrupt the traditional way intellectual property is being transacted and to become the World’s Next Web3 Patent Office. PatentX will be releasing an NFT collection of the most historic patent innovations this early March and encourage interested individuals to stay tuned for their launch.

On April 2, 2022, Team carSEAL will represent Georgia Tech in the 6^th annual ACC InVenture Prize Competition hosted this year by Florida State University. Team members Shovan Bhatia, Joshua Cruz, Nicholas Lima, Derek Prusener, and Giancarlo Riccobono will compete against other teams in the ACC Conference for a chance to win up to $30,000 in prizes. 

carSEAL began with five biomedical engineering students collaborating on a capstone project. After being accepted into the highly sought-after Mayo Clinic Capstone Project, they received mentorship from Dr. Rabih Tawk, a world-renowned neurosurgeon. With his guidance, they learned that surgeons currently lack the tools to close the carotid artery after endovascular procedures. Through a pragmatic approach, the team developed 100+ conceptual designs and iterations. After numerous discussions with attending surgeons across the nation and preliminary testing, they developed carSEAL – a vascular closure device for the carotid artery. 

So far, the team has found the InVenture Prize process to be exhilarating.

“Through each round of this process, we have seen incredible teams working on impactful projects and it is exciting to be surrounded by such brilliant minds from numerous backgrounds. It has been especially rewarding working with so many supportive advisors from Georgia Tech, who have been through the startup process and have freely offered their expertise. Along each step of this process, we have learned something new to refine our pitch and ensure we are presenting our most competitive self at the ACC.”

Currently, aside from preparing for the ACC InVenture Prize, the carSEAL team is performing benchtop lab testing to evaluate its efficacy in animal models. Soon after, the team will be moving to pre-clinical studies on their path to obtaining FDA clearance before carSEAL is commercialized. Winning the ACC InVenture Prize would help them gain more traction and gather sufficient funds to help them with this process.

“I am extremely proud of our team’s achievements in the short 6 months that we have worked together. carSEAL has gained a lot of traction already and we are excited to see how far we can take this, hopefully bringing carSEAL to clinical practice within a few years,” Bhatia stated.

The Georgia Tech community can support carSEAL in the competition by voting for them for the People’s Choice Awards by visiting: https://accinventureprize.com/peoples-choice-voting. Online voting begins March 28.

Two faculty members from the H. Milton Stewart School of Industrial and Systems Engineering received CAREER awards from the National Science Foundation (NSF), recognizing early-career contributions in both research and education. Assistant Professors He Wang and Siva Theja Maguluri received the award, the most prestigious of its kind awarded by the NSF, which carries a five-year term.

In addition to $500,000 in funding, which will help support the faculty member as well as their team of Ph.D. students, Wang said it provided recognition and validation for their respective research agendas.

“It’s great because it helps fund our work and will provide opportunities to support our students in this continued research,” he said. “But it also helps us to build connections with industry partners, who see the importance of our work, and allow us to implement some of it into the real world.”

Wang’s research focuses on supply chain and logistics in transportation. This particular award will fund research that seeks to design digital marketplaces for the freight industry. Describing it as a rideshare, like Uber, for trucking, Wang said that the goal of the research is to design online digital marketplaces that help truckers connect with shippers, eliminating a brokerage process plagued by inefficiency that can cost drivers both time and money.

“The idea here is to improve supply chain efficiencies and also the earning reliability of these truck drivers,” he said.

For an industry that is among the largest in the country, and indeed the most popular in more than half the country’s states, the research could have far-reaching implications.

Maguluri’s research, meanwhile, addresses optimization challenges in reinforcement learning and cloud computing, both of which are key areas of progress in the ongoing artificial intelligence revolution. The revolution is powered by the development of novel algorithms and breakthroughs in cloud computing infrastructure that can collect, store, and process large amounts of data.

“Even though neural networks were known about 50 years ago, AI breakthroughs only happened in the last 15 years,” Maguluri said. “This is because computers weren’t powerful enough earlier, and it was hard to get access to large computing power.”

Now, AI researchers can utilize massive data centers run by companies like Amazon, Microsoft, or Google.

Despite the progress, however, there are tradeoffs that affect optimal performance, and theory often lags behind practice. With this award, Maguluri and his lab will pursue studies in both reinforcement learning and cloud computing to develop optimal scheduling algorithms for cloud computing data centers that make both more efficient and, thus, further advancement in the field.

Even a global pandemic cannot slow the acceleration of new technologies and evolving technologies that has become the disruptive norm of our lives over the past decade.

Big data, global connectedness and the digitization of almost everything are driving a whirlwind of change that touches every aspect of our lives.

Georgia Tech continues to be at the center of that of that maelstrom of progress, pushing the cutting edge, developing and influencing advances and being an insistent voice for ensuring those advances are shared as broadly as possible.

Five faculty members share what they see as major forces impacting the coming year and beyond.

Microchip shortage will drive manufacturing to US and other supply chain changes

One of the big technology and supply chain stories of 2021 was the global shortage of microchips that impacted huge parts of the business world. One of the more visible impacts of that shortage was in the automotive field.

According to industry experts, the microchip shortage cost the automotive business $210 billion in revenue in 2020 driving prices up for new and especially used vehicles throughout the year. Dr. Madhavan Swaminathan, Georgia Tech’s John Pippin Chair in Microsystems Packaging and Electromagnetics, says the industry’s focus on finding solutions will bring noticeable change in the coming year.

He says early word of a trend in moving chip manufacturing to the United States will become a big focus in the coming year as well as auto manufacturers and other industries re-examining just-in-time supply decisions as they build inventory. 

Advances in addressing bias in AI bolsters inclusion

In computer science circles, it is no longer any sort of surprise that there can be bias in certain applications of artificial intelligence and machine learning. Bias can stem from a range of factors from the data used to software design to the situation where AI is being used.

How to know what to show each user with different world views in search or newsfeeds is quite different than making sure that software used for healthcare works for everyone. For example, sometimes a data set, even a quite large one, may not be representative.

There are close to 100,000 cases of skin cancer in the U.S. a year, and it is difficult to detect, especially the darker someone's skin tone is.

Machine learning researchers are making huge advances in detecting skin cancer, but a big limit is that the data they are using comes from light-skinned populations.

Knowing this problem exists opens the door to using data and artificial intelligence to improve detection for all. Dr. Deven Desai, a law and ethics professor in Georgia Tech’s Scheller College of Business, says in the coming year, because this potential for bias is known, we will become much better at identifying bias from wherever it may come and addressing it to limit harm.

The focus in the coming year will be on making the searching and sifting tools of AI and machine learning more attuned to potentially skewed results. This focus will bring better, more inclusive results.

Digital twins drive safety, efficiency and savings in construction

Think of them as the ultimate in interactive blueprints that can actually communicate to owners about building performance. The idea of a digital twin is not new. Building an exact match, digital version of a construction project is commonplace in construction now and has been for years. Architectural drawings, CAD images, or BIM images would all be considered “twins” in a way.

The advances that are happening now with true digital twins and that will be taking off in the coming year are in what you can do with and learn from a much more robust digital twin.

"Digital twinning is about the building and all the components that are in the building. Where they are, what condition they're in, all kinds of qualities," says Russell Gentry director of the Digital Building Lab at Georgia Tech.

In the coming year, Gentry expects the idea of using a digital twin will grow as its uses expand - monitoring for maintenance needs, identifying potential problems like leaks or water damage, dialing in HVAC system efficiencies - just a few of the changes that are happening or soon will be. Digital twins will be used to improve building safety, efficiency and even retrofitting existing buildings with new and improved technologies.

The automation and improvements that can be achieved will be a powerful force in construction and building management.  

Technology led up-skilling drives job agility that will increase worker satisfaction and productivity

In the U.S. alone, November 2021 saw more than four and a half million people quit their jobs, the biggest spike on record and continuing a streak of transition and upheaval. As the pace of change continues to increase, we need to be able to rapidly reconfigure workforces to address new challenges.

Ashok Goel, professor of computer science and human-centered computing in the School of Interactive Computing, has been watching the rapid changes in the job market. He sees technology as a solution to reskilling employees. 

“It is critical that we leverage technology to develop better tools to sync up employers and educators so that job seekers have clear paths to reskilling,” Goel says.

Using AI to match workers to jobs, to improve job performance and satisfaction are just a few of the efforts in the coming year that will ultimately result in improved worker well-being and productivity as well.

Covid public health crisis leads to public policy evolution

The pandemic has defined very clearly a strain in the relationship between scientists and some segments of the general public.

Some public policy makers, as a reflection of that divide, have made decisions related to public health that do not always match generally accepted science. For academic leaders in public policy like Dr. Cassidy Sugimoto, the Marie Patton School Chair in the School of Public Policy at Georgia Tech, this is one of the biggest challenges our society and people making public policy will face in the coming years.

Bridging the divide made clear by Covid and building the relationships that will result in better policy will be an effort that will have impact for decades.

“In many ways we’re setting the stage for the other looming global crises that we’re being faced with like climate change, like issues around social justice.

All of those are going to take the same kind of navigation in communication between the public between science and between policy makers and not just within regions but globally,” said Sugimoto.

It’s a challenge that she and her colleagues have dedicated their careers to taking on.
