​Brief Academic profile:

I received a PhD in Chemical Engineering from the Indian Institute of Technology Kanpur and continued my post-doctoral research work at the Technical University of Kaiserslautern, Germany. My master's (M. Tech) and bachelor's (B. Tech) in Chemical Engineering are from IIT Kanpur and Calcutta University, respectively. My PhD thesis is focused on the structure and properties of mixed-thiol self-assembled monolayers on gold nanoparticles using molecular simulations. My research interests are the computational investigation of polymers' interfacial properties, responsive surfaces, and hydro-gels, calculation of free energy using MD and MC.
