Professor Dan Esposito
Group Advisoresposito220
Daniel (Dan) Esposito received his B.S. in Chemical Engineering from Lehigh University and his Ph.D. in Chemical Engineering at the University of Delaware. After studying as a postdoc at the National Institute of Standards and Technology (NIST), he became an Assistant Professor in the Department of Chemical Engineering at Columbia University. At Columbia, he leads the Solar Fuels Engineering Lab, which combines its expertise in electrochemical and catalytic sciences with core chemical engineering principles to develop design rules for innovative electrochemical and solar energy conversion technologies. Prof. Esposito is a recipient of the National Science Foundation CAREER award, and his lab receives funding from a combination of federal agencies and industrial sponsors.

Postdocs and Ph.D. students

Xiangye Liu


Xiangye grew up in Hebei Province of China and attended Hebei University where he received his B.S. in chemistry. Then he attended Peking University where he worked under Prof. Fuqiang Huang on novel nanomaterials for electrocatalysis applications. After receiving his phD degree from Peking University, he came to Columbia University to investigate 2D materials for CO2 electrochemical reduction. Outside of lab he likes to walk in the park, play badminton and have fun with his friends.

Jack Davis
Ph.D. Student

jack 220

Jack is a native of Columbus, Ohio, and received his B.S. in chemical engineering from The Ohio State University. At OSU, he researched solid oxide fuel cells and oxidative dehydrogenation with the Ozkan lab group.  His current research interests include electrocatalysis, solar fuels generation, and electrochemical flow cells.  Jack volunteers as a high school math and science tutor through Columbia’s Dual Discovery Center. His favorite color is blue and he is a shameless fan of Star Wars.

Anna Dorfi
Ph.D. Student


Anna grew up in Akron, Ohio and received her B.S. in Chemical Engineering at The Ohio State University. Before coming to Columbia, she was on a Fulbright grant doing research on using anodized aluminum substrates for perovskite solar cell applications at the MPI for Polymer Research. Her current research interests include studying the bubble dynamics in water electrolysis, electrochemical flow cells, and solar fuels generation. Outside of lab, Anna enjoys Ultimate Frisbee, running and finding the best food in NYC.

Marissa Beatty
Ph.D. Student


Marissa received her B.S. in chemical engineering from Michigan State University. Now a Ph.D. candidate at Columbia University, Marissa’s research focuses on developing membrane coated electrocatalysts for a variety of solar fuels applications. Outside of research you can find Marissa practicing ballet, Texas hold ’em, and re-watching Jurassic Park (or any other 90s films).
