I am currently a Postdoc, working on the project "Artificial Intelligence Supported X-ray Imaging for Sustainable Metal Manufacturing". Prior to this, I spent 2.5 years as a Postdoctoral Researcher at Empa – Swiss Federal Laboratories for Materials Science and Technology, where my work combined computational and experimental approaches. We developed coupled CFD-DEM models to investigate particle behavior during Laser Directed Energy Deposition (LDED), performed in-situ synchrotron imaging of laser-induced powder stream dynamics, and contributed to the CALPHAD based alloy design of precious metals—including gold, silver, and platinum alloys in collaboration with industrial partners Richemont and Neoshapes. My PhD research, registered at IIT Kanpur and carried out at IIT Kanpur (India) and Purdue University (USA), focused on the investigation of dynamic laser beam interaction and melt pool evolution in laser-assisted metal additive manufacturing. My Master’s thesis at IIT Kanpur explored melting modes and keyhole instabilities in laser welding of Ti6Al4V, combining mesoscale thermo-fluidic modeling in OpenFOAM with experimental validation.
