Biography
Dr. Ray obtained her Ph.D. from Visva-Bharati University in 2015. She then received her postdoctoral training, first from the Max Planck Institute for the Physics of Complex Systems, Germany, and then from Tel Aviv University, Israel. Later, she joined IIT Tirupati as a DST-INSPIRE Faculty. Prior to joining IISER Berhampur, she was working as an inaugural Elizabeth Gardner Fellow at the School of Physics & Astronomy, University of Edinburgh, UK.

Fluctuations in Single-Molecular Biophysical Processes: Dynamics and Energetics
Fluctuations are inevitable in all sorts of physical systems, irrespective of whether it is macroscopic or microscopic in nature. Usually, the environmental fluctuations appear as noise, and they particularly affect the dynamics of small-scale systems where such influences can not be neglected as infinitesimal perturbations. A cellular system usually operates out of equilibrium with high fluctuations, yet biophysical processes find a cost-effective way towards completion with high accuracy. In this project, I aim to explore the dynamics and thermodynamics of such processes at the single molecule level.
