Jacqueline A. Dowling (Jackie) is a doctoral candidate in chemistry at the California Institute of Technology with a minor in environmental science and engineering. Her Ph.D. research focuses on energy storage from both a systems and technical perspective. She works with macro-scale models to understand the roles of energy storage in low-carbon electricity systems. In lab, she develops catalysts to improve electrolytic hydrogen production. Her advisor is Caltech chemistry professor Nathan S. Lewis, and they collaborate closely with Ken Caldeira at Carnegie Science.
