Dr. Julia Greenwald currently serves as an ARPA-E Fellow. Her interests include developing circular supply chains, novel mining and mineral processing technologies, and new helium production methods.

Dr. Greenwald earned her Ph.D. in physical chemistry from Columbia University, with support from the National Science Foundation Graduate Research Fellowship Program. Her research in the lab of Professor Latha Venkataraman investigated electron transport in single-molecule circuits. During her Ph.D., Dr. Greenwald measured the world’s highest switching ratio for a single-molecule device and studied how the solvent environment impacts device properties. Dr. Greenwald also served as a Fellow at Columbia Technology Ventures, where she analyzed the commercial potential of university research.

Dr. Greenwald holds an M.S. in analytical chemistry from the University of Washington and a B.A., magna cum laude, in chemistry from Carleton College. She previously researched thin-film solar cells at the National Renewable Energy Laboratory in Golden, CO and, as a Fulbright Research Fellow, biofuel production from Antarctic microalgae in Punta Arenas, Chile.
