Indian Institute of Technology Madras (IIT Madras), Chennai, India.
Awarded IIT Madras Institute postdoctoral fellowship, working on charged particle-particle collision and particle trajectories with relevance to cloud microphysics in a turbulent background field which is modelled as a stochastic fluctuating background flow. This is expected to drive the collision process in clouds.

Worked on charged particle-particle collision and particle trajectories with relevance to cloud microphysics in a project funded by ICSR, IIT Madras, Chennai, India. Clouds are mainly composed of water droplets and ice particles. At small length scales, there are physical as well as chemical processes like cloud condensation nuclei (CCN) activation, condensation, evaporation, collision and coalescence of droplets, which collectively referred to as cloud microphysics. The physics occurring at these length scales dictates the droplet size distribution evolution which in turn influences the precipitation of rain forming clouds. This requires a dedicated study of the cloud microphysics. I was tasked with the study of charged particle-particle interactions in clouds.
My doctoral work done at IISc Bangalore, I studied the hydrodynamic stability of unbounded shear flows namely, jets in crossflow, particle-laden planar jets, particle-laden round jets and particle-laden annular swirling jets. I performed numerical simulations of jets in crossflow using an open source incompressible code GERRIS to understand the flow field. The problem of the hydrodynamic instability of jet in the presence of crossflow was studied by following the asymptotic solution of the flow field in the limit of thin shear layer and weak crossflow developed by Kelly and Alves (Phil.Tans.Royal .Society, 2008). Performed LSA to look at the modification of shear layer instability of the jet in presence of a weak crossflow. For my second part of my thesis, I looked at particle-laden open shear layer flows where I derived local volume averaged equations to account for the presence of particulate phase (two fluid and two-way coupled formulation). Linearizing the two-fluid equations, I looked for exponentially growing unstable modes in the context of particle-laden planar jets, particle-laden round jets and particle-laden swirling jets. I was a teaching assistant for Fluid Mechanics (ME201) course (fall of 2018) offered in the department of Mechanical Engineering, IISc Bangalore.
