Saumya Ramanathan – Biography

Saumya Ramanathan Ph.D

Dr. Ramanathan obtained her Ph.D. at the University of Arizona, in the lab of Dr. William R. Montfort, where she studied the interplay between nitric oxide signaling and angiogenesis as they pertain to cancer maintenance. For her post-doctoral studies, Dr. Ramanathan went to Dr. Patrick Ryan Potts' lab at UT Southwestern Medical Center in Dallas. There she studied the biochemical functions of MAGEs, a group of proteins that are restricted to expression in the germ line but aberrantly expressed in many cancers.

At Fisk University, Dr. Ramanathan is pursuing her passion for teaching and mentoring. Her lab works on cancer-testis antigens and the role they play in the initiation or sustenance of cancer cell phenotypes. In addition, Dr. Ramanathan's lab studies epigenetics and the role of chromatin modifiers in cancer. She is also a mentor in the Fisk-Vanderbilt Bridge to Ph.D. Program.
