Andrew Bergman

G7 - Applied Physics

Andrew is studying an approach for direct air capture of atmospheric carbon dioxide using a new process, the alkalinity concentration swing (ACS), which describes the shift in equilibrium dissolved inorganic carbon content of a solution as a function of the concentration of alkalinity. His approach implements capacitive deionization to concentrate aqueous carbonate solution, driving the ACS. Beyond his lab work, Andrew works on justice-based frameworks for equitable deployment of carbon dioxide removal and other methods for responding to the climate crisis through collective governance, ownership, and operation of infrastructure and industry. Andrew is also an organizer and member of the Harvard Graduate Students Union and is always available to speak about our collective struggle for social justice on campus. Andrew received an A.B. in Physics from Princeton University.

Eric Fell

G6 - Materials Science & Mechanical Engineering

Eric is from Vancouver, Canada where he received his BSc in Chemistry at Simon Fraser University. In his undergrad, under the supervision of Prof. Gary Leach, he focused on photonics and electrochemical catalyst characterization. He also spent time in Germany developing water splitting catalysts and toxic gas sensors at Ludwig-Maximilians-Universität München and the Universität Paderborn. He is currently exploring high-throughput electrochemical techniques for the screening of redox-active molecules for aqueous organic flow batteries.  Here is a video of him presenting our group research. While he is constantly excited about energy storage, he also has a passion for nuclear science, CO2 capture, and space exploration.

Toly Rinberg

G6 - Applied Physics

Toly is an Applied Physics Ph.D. student working on a new process — the alkalinity concentration swing — for direct air capture of carbon dioxide. The approach is based on concentrating an alkaline solution that has been exposed to the atmosphere and loaded with dissolved inorganic carbon. He is specifically focused on experimentally testing whether reverse osmosis technologies could be applied to drive the ACS, and is (for now) the only group member who doesn't regularly apply voltage to electrodes. Beyond lab work, his interests include understanding and communicating how to equitably scale-up carbon dioxide removal, as well as developing governance models for public ownership of carbon dioxide removal. He's a Harvard Graduate Student Union steward in SEAS and is happy to be a resource to any student worker. Toly has a M.S. in Biophysics from Stanford University, and a B.S. in Physics and Math from Brandeis University.

Jordan Sosa

G4 - Materials Science & Mechanical Engineering

I received my Bachelor of Science in Engineering Physics from the University of Tulsa, where I pursued different research areas from carbon electrode materials to optics to metallic glasses. By combining cycling experiments of static cells for faster and less noisy data with simulations of what happens inside the porous electrodes, I hope to better understand the effects from 1. physical properties of the electrode, 2. transport, chemical, and electrochemical properties of the electrolyte, and 3. the interface between those two phases. I am also a big fan of using open-source platforms to model and analyze our experiments.
