Hello, and welcome to my homepage!

I am a computational materials scientist, currently working with Prof. Conrard Feugmo at the Feugmo research group in the department of Chemistry at University of Waterloo as a postdoc. Here, we are trying to modify phase field crystal models by incorporating three-point correlation functions for complex crystal structures in order to study defect interactions in complex concentrated alloys and diffusion of Lithium ions through graphite electrodes in a Lithium-ion battery. In addition, we are also trying to come up with a phase field model for corrosion of metallic systems in molten salts, with material parameters informed by atomistic simulations.

Before coming to Canada, I completed my PhD from the department of Metallurgical Engineering and Materials Science at Indian Institute of Technology Bombay, with Prof. M P Gururajan and Prof. Prita Pant. My PhD thesis focused on the study of the effect of dislocations on phase transformation phenomena using phase field simulations. Essentially, we study the effect of elastic interaction between dislocations and the solutes in a two-phase system leading to interesting phase transformation phenomena.

We have also used the phase field dislocation dynamics (PFDD) code developed to look at the equilibrium stacking fault widths in different face-centered cubic alloy systems. The generalised stacking fault energy is incorporated from atomistic or density functional theory calculations performed by our collaborators at Prof. Vaishali Shah’s group in University of Pune. In addition, during the early years of my PhD, I was also part of an ab-initio study of the effect of electron-phonon interactions on the total energy and hence, the stability of group-IV semiconductor polymorphs, such as Si and C.

As part of an Overseas visiting doctoral fellowship (SERB-OVDF 2019), I have also spent six months at GPM2-SIMaP, Universite Grenoble Alpes with Prof. Marc Fivel’s research group. During this fellowship, I worked on an in-house discrete dislocation dynamics simulation package called NUMODIS, trying to develop an algorithm to model slip transfer. This was followed by another effort in collaboration with the same team to implement fast Fourier transform based elastic stress computations in NUMODIS (the Discrete-Continuous Method). This is an ongoing project.
