Curriculum Vitae
Faculty Profile

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.

Natalie Labrador
Ph.D. Student


Natalie grew up in sunny southern California and attended University of California, Santa Barbara where she received her B.S. in chemical engineering. Now a Ph.D. candidate at Columbia University, Natalie’s research interests are solar energy conversion and photoelectrodes for solar water splitting. On cloudy days when she misses the sun she basks in front of the Esposito Lab’s high-wattage lamp solar simulator. Just kidding, that would be an extreme safety hazard.

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.
