About the Scientist

Sarma studies the mechanisms of RNA-mediated epigenetic gene regulation to understand how the loss of chromatin modifier-RNA interactions impacts cellular function.

Sarma completed her graduate studies with a Ph.D. in biochemistry from Rutgers University. She conducted her postdoctoral training at the Massachusetts General Hospital-Harvard Medical School, and joined The Wistar Institute in 2016 as an Assistant Professor.

The Sarma Laboratory

The Sarma laboratory is interested in the mechanisms of epigenetic gene regulation, or how the dynamic modifications of the architecture of chromatin, the complex of DNA and proteins within the nucleus of our cells, impacts gene expression and cellular function. The lab investigates consequences of epigenetic alterations in neuronal cancers and neurodegenerative diseases using a combination of biochemistry, cell and molecular biology with genome wide approaches to gain mechanistic insight into how chromatin architecture is modified in disease. The goal is to identify new pathways and interactions that can be targeted to correct these epigenetic perturbations.

Research

Current research interests in the lab include:
