About me

I joined IIT Jodhpur as an Assistant Professor in Mechanical Engineering in May 2021.

I completed my B.Tech and M.Tech in Mechanical Engineering from IIT Kharagpur. During my undergraduate research with Prof. Ghosh Moulic, I became interested in numerical methods for modeling fluid flows, particularly those with discontinuities such as shocks and multiphase phenomena.

For my B.Tech thesis, I evaluated numerical schemes for shock modeling in an adaptive mesh framework. My M.Tech thesis involved developing an in-house code for simulating mixed convection film condensation, using coordinate transformation and a body-fitted mesh to address matrix stiffness, solved via perturbation methods.

I pursued my Ph.D. at the University of Massachusetts Dartmouth under Prof. Mehdi Raessi, focusing on two-phase flows interacting with moving rigid bodies. Due to significant interface deformation, I used the Volume-of-Fluid method on a fixed grid, avoiding remeshing and enabling large topological changes. This solver was applied to Ocean Wave Energy Converters, yielding key insights into dynamic similarity. As a Postdoctoral Fellow at UMass Dartmouth, I studied droplet dynamics from spray-wall interactions and developed a phase-change solver for evaporating, deforming interfaces.
