Profile Summary

I have completed PhD working on Metal AM from Indian Institute of Technology Kanpur, India. During PhD I worked on LPBF processing of Ti6Al4V and AlSi10Mg. My research involved using computational modeling and experiments to investigate the thermo-fluidic transport phenomena, solidification process, microstructure and mechanical properties of as-manufactured and heat treated materials post-LPBF manufacturing. I have considerable experience with COMSOL for modeling and simulations, Origin Pro for graphs, image analysis using FIJI and imageJ. I also worked on design, manufacturing and testing of cellular materials (periodic lattice structures), an area which still interests me. My experimental experience includes residual porosity analysis, optical micrograph analysis, LPBF equipment operation, single-scan and bulk sample manufacturing, sample preparation and microstructural analysis. At present I am making a transition to OpenFOAM for modeling and simulation.
