Soft Matter Physics Group

I completed Ph.D from Saha Institute of Nuclear Physics, Kolkata (India) in the year 2017. Afterwards, I joined as a Postdoctoral Research Associate at Kiel University in Germany where I collaborated with Deutsche Electron Synchrotron (DESY) in Hamburg, Germany. I earned Master’s in Physics from Indian Institute of Technology Kharagpur and the Bachelor’s degree from RKMR College Narendrapur under University of Calcutta (CU, Kolkata).

My primary areas of interest lie in the field of biophysical systems, nano-bio interfaces and liquid surfaces. I investigate the surface and interfaces of biomolecular films, especially, to understand their structure and dynamics in presence of exogenous molecules such as protein, drug and synthetic nanoparticles. I use various state-of-the-art experimental tools including X-ray reflectivity (XRR), Grazing incidence diffraction (GID), Grazing incidence small angle X-ray scattering (GISAXS), neutron scattering and also thermodynamic measurements based on the Langmuir-Blodgett methods. Also, I experimentally investigate the highly non-equilibrium dynamics such as capillary wave dynamics, electron solvation dynamics at the liquid surfaces and interfaces for the fundamental understanding of the highly non-equilibrium processes at atomic length scale and on sub-ns timescale.

In summary, I utilize the state-of-the-art physics tools at nano-bio interfaces to disentangle the challenges posed by the biophysical systems at their surface and interfaces for the fundamental understanding of physics of life. I also investigate the structure and thermodynamics of biomolecular systems having direct and/or indirect biomedical, biosensing and industrial applications. I collaborate with DESY (Germany), ESRF (France), APS (ANL, USA), Photon Factory (Japan) for the synchrotron X-ray studies.
