Assistant Professor of Pharmacology
Biography
The Bhattacharyya Lab studies molecular mechanism of kinase signaling, especially in the context of learning, memory and neuropathological conditions. Dr. Bhattacharyya received her PhD in Computational Biophysics at the Indian Institute of Science, Bangalore where she used molecular dynamics simulations and graph theory to study allosteric communication in proteins and its complexes with RNA/DNA. She made a transition into experimental biology during her postdoctoral studies at the University of California Berkeley as a Human Frontier Science Program Long Term Fellow. She used structural biology, single-molecule microscopy, and native mass spectrometry along with computational techniques to study the molecular mechanism of regulation in a calcium/calmodulin-dependent protein kinase that is critical for learning and memory. The Bhattacharyya Lab takes an integrative approach to understand the molecular mechanism of cellular signaling using both experimental and computational techniques.
