I am a physicist pursuing research at the interface of soft matter photonics, soft matter physics, nanophysics, optical engineering, optics, ultrafast optics and optical technique development. I have investigated the light-matter interaction, structural transition dynamics, crystallization, particle contact force distribution and mechanics of soft matters (magnetic nanofluid, magnetic emulsion, colloidal gel and granular matter), particularly their interaction with external stimuli (field, stress etc.) at different length scales, using existing experimental techniques (mainly optical) and also by developing new techniques, which also includes the design of optical lens systems (microscope objective lens etc.).

I been working as a Research Assistant Professor in SRM Research Institute and Department of Physics and Nanotechnology, SRM Institute of Science and Technology (formerly known as SRM University) since September 2016. I have developed a light scattering technique to study the structural transitions in magnetic field polarizable soft matters, during my doctoral (Ph.D.) research at Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam, India.

During my postdoctoral tenure at Max Planck Institute for Polymer Research, Mainz, Germany, I have worked on the “determination of 3D structural topological origin of elasticity in colloidal gel under compressive strain”.

During postdoctoral research at Max Planck Institute for Dynamics and Self-Organization, Goettingen, Germany, I have designed and developed a stress resolving two photon fluorescence microscope to measure 3D contact force distribution in hard, frictional granular packing of ruby spheres.
