About Candidate
Currently, I am serving as an Assistant Professor at Sandip University, Nashik, Maharashtra. I bring with me a well-rounded experience that includes industrial exposure, academic teaching, and advanced research. Previously, I worked for two years as a Maintenance Engineer at Fabetto Ecotech Private Ltd., and I have also completed a two-year postdoctoral research tenure at IIT Bombay.
During my postdoctoral research, I focused on rolling and hot deformation of magnesium alloys. Specifically, I carried out multi-pass hot rolling of cast Mg-3Al-0.2Ce alloy sheets at temperatures ranging from 300°C to 400°C to study the influence of rolling parameters and alloying elements on microstructure refinement, mechanical properties, and corrosion resistance. My work offered significant insights into the roles of precipitates, twinning, and dynamic recrystallization (DRX) in tailoring the microstructure and texture of the alloy.
My doctoral research at the Department of Metallurgical and Materials Engineering, IIT Roorkee, focused on welding and metal processing, culminating in several journal publications and a patent. Prior to that, my master’s research involved thermo-mechanical processing of zirconium-based alloys, where I used hot compression testing on the Gleeble-3800 simulator to develop processing maps and evaluate the hot workability of Zr alloys.
Throughout my academic and research journey, I have gained hands-on experience with a wide range of equipment and techniques, including PIV, LDV, DIC, Rheometers, SEM, EBSD, XRD, and mechanical testing systems. My expertise spans hot deformation, microstructure and texture analysis, metal matrix composites, fatigue, and fracture.
Having earned both my M.Tech and Ph.D. from IIT Roorkee, and completed my postdoctoral training at IIT Bombay, I have acquired a robust foundation in Metallurgical and Materials Engineering, complemented by a strong research orientation and a passion for teaching.

Thermo-mechanical processing of Zr based alloys Hot workability of Zr alloy has been investigated by means of hot compression test using Gleeble-3800. Hot compression test was performed in the temperature and strain rate range of 700 to 1000oC and 0.01-10s-1, respectively.Deformation behaviour was characterized with the help of processing maps using Dynamic Material Model (DMM) and modified DMM.
Three-dimensional material flow characterization using tracer insert technique: Three-dimensional material flow and strain accumulation during friction stir processing (FSP) were characterized using embedded tracers extracted from the parent workpiece material. The use of identical tracer and base materials ensured reliable strain quantification. Tracers positioned in transverse, longitudinal, and processing-direction orientations enabled reconstruction of the full three-dimensional material flow field, from which three dominant material transport modes were identified. In-situ material flow visualization via Particle Image Velocimetry: An in-situ Particle Image Velocimetry (PIV) technique was employed to investigate material flow during friction stir welding/processing (FSW/FSP). Flow around the rotating tool pin was visualized using microspherical glass tracers suspended in a transparent viscoplastic medium. Two-dimensional velocity fields were obtained by tracking tracer trajectories in real time. Computational modeling of material flow in COMSOL Multiphysics: Finite-element simulations were performed in COMSOL Multiphysics to corroborate the experimental PIV observations. The viscoplastic medium was modeled as an incompressible, single-phase fluid with non-Newtonian behavior, described by a power-law constitutive model. Rheological parameters were experimentally determined using a rotational rheometer (Anton Paar MCR 100)
