Assistant Professor of Medicine

Research Interests: Nudix hydrolases; Isoprenoid pathway as a target of protozoan parasitic diseases; PI3K/mTOR pathways

Background

Dr. Sandra Gabelli is an Assistant Professor of Medicine in the Biophysics and Biophysical Chemistry and Oncology departments. She studies the molecular mechanisms of signal transduction and oncogenic activation in the PI3K/mTOR pathways. She is also studying the isoprenoid pathway as a target of protozoan parasitic diseases.

Dr. Gabelli holds a PhD from Johns Hopkins University and completed postdoctoral research at Johns Hopkins before joining the faculty.
