Steven C. Freilich is currently executive-in-residence in the Joint Institute for Strategic Energy Analysis at National Renewable Energy Laboratory, having recently retired from DuPont after a 33 year career. For the last 12 years of his DuPont career, he served as the director of materials science in DuPont Central Research and Development. In that role, Freilich was responsible for developing and implementing the technology growth strategies in rapidly moving areas such as materials for energy, displays, and biomedical applications. He used his experience to impact corporate innovation through leadership at the interface of technology and markets.

During his tenure as director of materials science, Dr. Freilich held the additional position of CTO of the DuPont Electronics and Communication Platform, and was appointed as the chief technology advocate for North Asia. He has served on the boards of the United States Display Consortium, DuPont Photonics Technologies, the DuPont-MIT Alliance, and was the vice chair of both the advisory panel for the Center for Revolutionary Solar Photoconversion and the advisory committee for the Clean Energy Manufacturing Analysis Center in the Department of Energy. He has also served on the advisory boards for Sandia National Laboratory, the National Renewable Energy Laboratory, and the National Research Council of Canada.

Judith Greenwald, Class of 1982, is a former U.S. Department of Energy (DOE) executive with more than 30 years of policy experience working in government and the nonprofit sector. She is a graduate of the School of Engineering and Applied Science and returned as a fellow in spring 2018. During her time at the center, she collaborated on research, lectured, advised students, brought in speakers, and convened industry, government, and NGO leaders. She liaised with the undergraduate student group, Princeton University Energy Association, to facilitate the group’s inaugural conference to examine New Jersey’s power markets and policy reforms in April 2018. Greenwald guest lectured at the Keller Center for Innovation in Engineering Education and at Conversations on the Environment and Responsible Energy and Life. She organized “Accelerating Climate Action in the United States: What Are We Doing and What More Can be Done,” a September 2018 public conference, featuring keynote speaker Tammy Snyder Murphy, First Lady of New Jersey. In her lectures, Greenwald emphasized that the causes of and solutions to climate change rest at the intersection of public policy, technology, market forces, and human behavior. Greenwald is now Executive Director of the Nuclear Innovation Alliance.

Darren Hammell, Class of 2001, is co-founder and president of Princeton Power Systems, a designer and manufacturer of microgrid and battery solutions. He founded the company as an undergraduate at Princeton’s School of Engineering and Applied Science and the company is now a global leader with thousands of deployments across North America, Europe, Africa, and the Caribbean. Hammell returned for a fellowship during which he provided support to start-up companies that have been founded at the Andlinger Center. He led discussions and served as a panelist at the 2018 Annual E-ffiliates Retreat and lectured on his experience commercializing energy technology during the Andlinger Center’s executive education module for Young Global Leaders in July 2018. He also led the development of a course on commercializing energy technologies at the Andlinger Center.

Anthony Ku is the director of advanced technologies at the National Institute of Clean and low carbon Energy (NICE) and chief technology officer of NICE America Research. NICE is a corporate-level R&D division of China Energy, the world’s largest electric utility. In 2019, China Energy operated over 220 GW of generation capacity, and produced 15% of China’s electricity and 20% of its hydrogen. Ku oversees technology innovation efforts in the areas of carbon management, hydrogen refueling, systems optimization, and energy storage. He is also a current co-chair of the Business Advisory Board International Roundtable on Criticality, a consortium focused on critical materials and sustainable supply chains and a member of the National Academy of Science Condensed Matter and Materials Research Committee. At the Andlinger Center, Ku will collaborate with researchers from the Rapid Switch project on optimizing the retirement schedules for recently installed coal power plants in China to balance capital replacement costs and net-zero goals and investigating data sharing approaches to improving the transparency and sustainability of supply chains for critical materials in renewable energy. Ku earned a Ph.D. in chemical engineering from Princeton in 2004, a B.S. in chemical engineering from MIT in 2006, and a M.S. in chemical engineering Practice from MIT in 2007.

Harold May joined the Andlinger Center in September 2022 as a Gerhard R. Andlinger Visiting Fellow with a one-year appointment. May is Professor emeritus of Microbiology and Immunology at the Medical College of South Carolina, where he directed wide-ranging research related to microbial applications for organic pollutant remediation, biofuels, and synthesis of fuels and chemicals from CO₂. A fellow of the National Academy of Inventors, May is the founder of two companies focused on microbial production of fuels and chemicals. At Princeton, he will collaborate with Z Jason Ren on research to improve the efficiency and throughput of combined microbial-electrochemical methods for converting CO₂ into fuels and chemicals, with the aim of developing scalable systems that can be used to capture CO₂. To complement these efforts, May plans to organize a workshop at Princeton for the broader research community to identify key research challenges in microbial CO₂ capture and foster new collaborations.

Jean-Marcel Rax joined the Andlinger Center in September 2022 as a Gerhard R. Andlinger Visiting Fellow with a six-month appointment. Rax is a University Professor at Université de Paris-Saclay and École Polytechnique. Among his many accomplishments, Rax has served as Technical Adviser and Scientific Advisor to the French Atomic Energy Commission and as Director of the Laboratory for Plasma Physics and Technology at École Polytechnique. At Princeton, Rax is collaborating with Nathaniel Fisch on two projects related to plasma applications in fission and fusion energy. One project will examine reactors for rotating magnetized plasmas to enable efficient reprocessing of spent fuel from nuclear fission. The other project focuses on how injecting pulses of electrons into Tokamak fusion reactors can be used to control the plasma motion and improve reactor performance.
