Aabha Sharma

PhD Student

Learn More

Aabha Sharma is a PhD-MPH student interested in ciliary membrane composition as it relates to cell signaling. Her major project focuses on the lipid composition of the ciliary membrane, with the overarching hypothesis that the lipid environment permits cell-signaling complexes to assemble in this special membrane compartment of the cell.
