Greetings! I am currently a postdoctoral fellow in the Department of Mechanical and Aerospace Engineering, IIT Hyderabad. We are investigating an interaction of a cavitation bubble with a confined bubble. During my PhD, I worked on interfacial flows, with a specific focus on a moving contact line dynamics with Dr. Harish N. Dixit and Dr. Lakshamana D. Chandrala. With the help of particle image velocimetry (PIV), we investigated the dynamics near the moving contact line in great detail. For more information, you can refer to the pre-print of our recently submitted paper in the Research tab. Moreover, I have explored other useful optical techniques like shadowgraphy, schlieren imaging, holography, interferometry etc. I am passionate about exploring a broad spectrum of fluid dynamics problems and am open to diverse research opportunities in the field.
