Crotty Alexander Lab

Principal Investigator


Dr. Laura Crotty Alexander completed her undergraduate and medical degrees at Duke University, followed by Internal Medicine residency and Pulmonary Critical Care fellowship training at Harvard. She has conducted research at Duke, the NIH, Massachusetts General Hospital and the UC San Diego where she is currently an Associate Professor of Medicine. She is also the Section Chief of Pulmonary Critical Care at the VA San Diego. She has been studying the health effects of e-cigarettes and vaping since 2013, and this remains the focus of the LCA Lab. Dr. Crotty Alexander also co-directs the first block of the UC San Diego School of Medicine with Dr. Erica Lin.
