Tequila A.L. Harris, a professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech, leads energy and manufacturing initiatives at the Strategic Energy Institute. Her research explores the connectivity between the functionality of nano- to macro-level films, components, and systems based on their manufacture or design and their life expectancy, elucidating mechanisms by which performance or durability can be predicted. She uses both simulations and experimentation to better understand this connectivity.
By addressing complex, fundamental problems, Harris aims to make an impact on many industries, in particular energy (e.g., polymer electrolyte membrane fuel cells), flexible electronics (e.g., organic electronics), and clean energy (e.g., water), among others.
Harris has experience in developing systematic design and manufacturing methodologies for complex systems that directly involve material characterization, tooling design and analysis, computational and analytical modeling, experimentation, and system design and optimization. Currently, her research projects focus on investigating the fundamental science associated with fluid transport, materials processing, and design issues for energy/electronic/environmental systems. Below is a brief Q&A with Harris, where she discusses her research and how it influences the energy and manufacturing initiatives at Georgia Tech.
- What is your field of expertise and at what point in your life did you first become interested in this area?
In graduate school, I aimed to become a roboticist but shifted my focus after realizing I was not passionate about coding. This led me to explore manufacturing, particularly scaled manufacturing processes that transform fluids into thin films for applications in energy systems. Subsequently, my expertise is in coating science and technology and manufacturing system development.
- What questions or challenges sparked your current energy research? What are the big issues facing your research area right now?
We often ask how we can process materials more cost-effectively and create complex architectures that surpass current capabilities. In energy systems, particularly with fuel cells, reducing the number of manufacturing steps is crucial, as each additional step increases costs and complexity. As researchers, we focus on understanding the implications of minimizing these steps and how they affect the properties and performance of the final devices. My group studies these relationships to find innovative manufacturing solutions. A major challenge in the manufacture of materials lies in scaling efficiently while maintaining performance and keeping costs low enough for commercial adoption. This is a pressing issue, especially for enabling technologies such as batteries, fuel cells, and flexible electronics needed for electric vehicles, where the production volumes are on the order of billions per year.
- What interests you the most in leading the research initiative on energy and manufacturing? Why is your initiative important to the development of Georgia Tech’s energy research strategy?
What interests me most is the inherent possibility of advancing energy technologies holistically, from materials sourcing and materials production to public policy. More specifically, my interests are in understanding how we can scale the manufacture of burgeoning technologies for a variety of areas (energy, food, pharmaceuticals, packaging, and flexible electronics, among others) while reducing cost and increasing production yield. In this regard, we aim to incorporate artificial intelligence and machine learning in addition to considering limitations surrounding the production lifecycle. The challenges that exist to meet these goals cannot be done in a silo but rather as part of interdisciplinary teams who converge on specific problems. Georgia Tech is uniquely positioned to make significant impacts in the energy and manufacturing ecosystem, thanks to our robust infrastructure and expertise. With many manufacturers relocating to Georgia, particularly in the "energy belt" for EVs, batteries, and recycling facilities, Georgia Tech can serve as a crucial partner in advancing these industries and their technologies.
- What are the broader global and social benefits of the research you and your team conduct on energy and manufacturing?
The global impact of advancing manufacturing technologies is significant for processing at relevant economy of scales. To meet such demands, we cannot always rely on existing manufacturing know-how. The Harris group holds the intellectual property on innovative processes that allow for the faster fabrication of individual or multiple materials, and that exhibit higher yields and improved performance than existing methods. Improvements in manufacturing systems often result in reduced waste, which is beneficial to the overall materials development ecosystem. Another global and societal benefit is workforce development. The students on my team are well-trained in the manufacture of materials using tools that are amenable to the most advanced and scalable manufacturing platform, roll-to-roll manufacturing, with integrated coating and printing tools. This unique skill set equips our students to thrive and become leaders in their careers.
- What are your plans for engaging a wider Georgia Tech faculty pool with the broader energy community?
By leveraging the new modular pilot-scale roll-to-roll manufacturing facility that integrates slot die coating, gravure/flexography printing, and inkjet printing, I plan to continue reaching out to faculty and industrial partners to find avenues for us to collaborate on a variety of interdisciplinary projects. The goal is to create groups that can help us advance materials development more rapidly by working as a collective from the beginning, versus considering scalable manufacturing pathways as an afterthought. By bringing interdisciplinary groups (chemists, materials scientists, engineers, etc.) together early, we can more efficiently and effectively overcome traditional delays in getting materials to market or, worse, the inability to push materials to market (which is commonly known as the valley of death). This can only be achieved by dismantling barriers that hinder early collaboration. This new facility aims to foster collaborative work among stakeholders, promoting the integrated development and characterization of various materials systems and technologies, and ultimately leading to more efficient manufacturing practices.
- What are your hobbies?
I enjoy cooking and exploring my creativity in this space by combining national and international ingredients to make interesting and often delicious fusion cuisines. I also enjoy roller skating, cycling, and watching movies with my family and friends.
- Who has influenced you the most?
From a professional standpoint, my research team influences me the most. After I present them with a problem, they are encouraged and expected to think beyond our initial starting point. This ability to freely think and conceive of novel solutions sparks many new ideas on which to build future ideas. The best cases have kept me up at night, inspiring me to think about how to approach new problems and funding opportunities. I carry their experiences and challenges with me. Their influence on me is profound and is fundamentally why I am a professor.

Amino acids are essential for nearly every process in the human body. Often referred to as ‘the building blocks of life,’ they are also critical for commercial use in products ranging from pharmaceuticals and dietary supplements, to cosmetics, animal feed, and industrial chemicals.
And while our bodies naturally make amino acids, manufacturing them for commercial use can be costly — and that process often emits greenhouse gasses like carbon dioxide (CO2).
In a landmark study, a team of researchers has created a first-of-its kind methodology for synthesizing amino acids that uses more carbon than it emits. The research also makes strides toward making the system cost-effective and scalable for commercial use.
“To our knowledge, it’s the first time anyone has synthesized amino acids in a carbon-negative way using this type of biocatalyst,” says lead corresponding author Pamela Peralta-Yahya, who emphasizes that the system provides a win-win for industry and environment. “Carbon dioxide is readily available, so it is a low-cost feedstock — and the system has the added bonus of removing a powerful greenhouse gas from the atmosphere, making the synthesis of amino acids environmentally friendly, too.”
The study, “Carbon Negative Synthesis of Amino Acids Using a Cell-Free-Based Biocatalyst,” published today in ACS Synthetic Biology, is publicly available. The research was led by Georgia Tech in collaboration with the University of Washington, Pacific Northwest National Laboratory, and the University of Minnesota.
The Georgia Tech research contingent includes Peralta-Yahya, a professor with joint appointments in the School of Chemistry and Biochemistry and School of Chemical and Biomolecular Engineering (ChBE); first author Shaafique Chowdhury, a Ph.D. student in ChBE; Ray Westenberg, a Ph.D student in Bioengineering; and Georgia Tech alum Kimberly Wennerholm (B.S. ChBE ’23).
Costly chemicals
There are two key challenges to synthesizing amino acids on a large scale: the cost of materials, and the speed at which the system can generate amino acids.
While many living systems like cyanobacteria can synthesize amino acids from CO2, the rate at which they do it is too slow to be harnessed for industrial applications, and these systems can only synthesize a limited number of chemicals.
Currently, most commercial amino acids are made using bioengineered microbes. “These specially designed organisms convert sugar or plant biomass into fuel and chemicals,” explains first author Chowdhury, “but valuable food resources are consumed if sugar is used as the feedstock — and pre-processing plant biomass is costly.” These processes also release CO2 as a byproduct.
Chowdhury says the team was curious “if we could develop a commercially viable system that could use carbon dioxide as a feedstock. We wanted to build a system that could quickly and efficiently convert CO2 into critical amino acids, like glycine and serine.”
The team was particularly interested in what could be accomplished by a ‘cell-free’ system that leveraged some process of a cellular system — but didn’t actually involve living cells, Peralta-Yahya says, adding that systems using living cells need to use part of their CO2 to fuel their own metabolic processes, including cell growth, and have not yet produced sufficient quantities of amino acids.
“Part of what makes a cell-free system so efficient,” Westenberg explains, “is that it can use cellular enzymes without needing the cells themselves. By generating the enzymes and combining them in the lab, the system can directly convert carbon dioxide into the desired chemicals. Because there are no cells involved, it doesn’t need to use the carbon to support cell growth — which vastly increases the amount of amino acids the system can produce.”
A novel solution
While scientists have used cell-free systems before, one of the necessary chemicals, the cell lysate biocatalyst, is extremely costly. For a cell-free system to be economically viable at scale, the team needed to limit the amount of cell lysate the system needed.
After creating the ten enzymes necessary for the reaction, the team attempted to dilute the biocatalyst using a technique called ‘volumetric expansion.’ “We found that the biocatalyst we used was active even after being diluted 200-fold,” Peralta-Yahya explains. “This allows us to use significantly less of this high-cost material — while simultaneously increasing feedstock loading and amino acid output.”
It’s a novel application of a cell-free system, and one with the potential to transform both how amino acids are produced, and the industry’s impact on our changing climate.
“This research provides a pathway for making this method cost-effective and scalable,” Peralta-Yahya says. “This system might one day be used to make chemicals ranging from aromatics and terpenes, to alcohols and polymers, and all in a way that not only reduces our carbon footprint, but improves it.”

Southern Company, Georgia Institute of Technology (Georgia Tech), Smart Wires, and other partners have announced that they are collaborating on a new U.S. Department of Energy-funded project. Scheduled for 2025, the project will jointly implement advanced power flow control (APFC) and dynamic line rating (DLR) technologies to support the connection of renewable energy sources and new demand more quickly.
This project, led by the Georgia Tech Center for Distributed Energy with professor Deepak Divan as Principal Investigator, was selected by the U.S. Department of Energy in November 2021 as one of four projects to receive funding for grid enhancing technologies (GETs) that improve grid reliability, optimize existing grid infrastructure, and support the connection of renewable energy. It will use Smart Wires’ APFC solution— SmartValve™—in a mobile deployment combined with its DLR software—SUMO—and also develop control algorithms that improve and fine-tune how these solutions can work in synergy to optimize use of the grid.
“The launch of this innovative project represents an important step toward more efficient and reliable integration of cleaner energy sources,” said Tim Lieuwen, interim executive vice president for Research at Georgia Institute of Technology. “This collaboration allows us to identify, develop and test new ways to manage the power grid in Georgia by co-deploying APFC and DLR technologies.”
While the effectiveness of these solutions is well documented in multiple third-party reports, such as RMI’s GETting Interconnected in PJM, this project will be the first large-scale implementation of both technologies together. It will specifically examine their combined impact and result in the development of design control algorithms to unlock the combined power of these solutions and maximize their efficiency.
SUMO identifies when lines have spare capacity based on real-time weather conditions, while SmartValves can redirect power flows to quickly utilize this spare capacity. This also applies in reverse, with SUMO identifying when the dynamic ratings of lines are less than the static rating. If it’s a hot day, for example, SmartValves can redirect power flows away from these circuits to others with capacity, reducing the risk of system faults while improving operational safety.
The mobile deployment of SmartValves can be installed and in-service within one week. This provides a rapidly deployable solution that avoids extended outages and can be easily moved between sites as system needs evolve over time.
“We’re delighted to provide both SmartValves and SUMO in this project to move the dial in terms of deploying multiple GETs in synergy and optimizing their use,” said Joaquin Peirano, General Manager for the Americas at Smart Wires. “The commitment of utilities like Southern Company to get the most from their existing grid with GETs, combined with the positive regulatory developments such as FERC’s recent Order 1920, positions the U.S. to capture the full value these technologies can provide on transmission grids.”
The project will be delivered in 2025 and will involve a one-year performance period to provide Southern Company with operational experience that can be shared with other utilities and pave the way for greater use of GETs in the U.S.

Eight Georgia Tech researchers were honored with the ACM Distinguished Paper Award for their groundbreaking contributions to cybersecurity at the recent ACM Conference on Computer and Communications Security (CCS).
Three papers were recognized for addressing critical challenges in the field, spanning areas such as automotive cybersecurity, password security, and cryptographic testing.
“These three projects underscore Georgia Tech's leadership in advancing cybersecurity solutions that have real-world impact, from protecting critical infrastructure to ensuring the security of future computing systems and improving everyday digital practices,” said School of Cybersecurity and Privacy (SCP) Chair Michael Bailey.
One of the papers, ERACAN: Defending Against an Emerging CAN Threat Model, was co-authored by Ph.D. student Zhaozhou Tang, Associate Professor Saman Zonouz, and College of Engineering Dean and Professor Raheem Beyah. This research focuses on securing the controller area network (CAN), a vital system used in modern vehicles that is increasingly targeted by cyber threats.
"This project is led by our Ph.D. student Zhaozhou Tang with the Cyber-Physical Systems Security (CPSec) Lab," said Zonouz. "Impressively, this was Zhaozhou's first paper in his Ph.D., and he deserves special recognition for this groundbreaking work on automotive cybersecurity."
The work introduces a comprehensive defense system to counter advanced threats to vehicular CAN networks, and the team is collaborating with the Hyundai America Technical Center to implement the research. The CPSec Lab is a collaborative effort between SCP and the School of Electrical and Computer Engineering (ECE).
In another paper, Testing Side-Channel Security of Cryptographic Implementations Against Future Microarchitectures, Assistant Professor Daniel Genkin collaborated with international researchers to define security threats in new computing technology.
"We appreciate ACM for recognizing our work," said Genkin. “Tools for early-stage testing of CPUs for emerging side-channel threats are crucial to ensuring the security of the next generation of computing devices.”
The third paper, Unmasking the Security and Usability of Password Masking, was authored by graduate students Yuqi Hu, Suood Al Roomi, Sena Sahin, and Frank Li, SCP and ECE assistant professor. This study investigated the effectiveness and provided recommendations for implementing password masking and the practice of hiding characters as they are typed and offered.
"Password masking is a widely deployed security mechanism that hasn't been extensively investigated in prior works," said Li.
The assistant professor credited the collaborative efforts of his students, particularly Yuqi Hu, for leading the project.
The ACM Conference on Computer and Communications Security (CCS) is the flagship annual conference of the Special Interest Group on Security, Audit and Control (SIGSAC) of the Association for Computing Machinery (ACM). The conference was held from Oct. 14-18 in Salt Lake City.
