Currently I am doing my Post-Doctoral Research in Hebrew University of Jerusalem and jointly working as a Visiting Scientist with Prof. Victor Steinberg. in Weizmann Institute of Science, Israel. We are studying fluid dynamics to see the intability on Non-Newtonian fluid/Visco-elastic fluid. The elastic instability is observed even in very samll Reynolds number and Weissenberg number

Previously I was working as a Post-Doctoral Researcher in IIT Madras, Tamil Nadu, India with Prof. Ragunathan Rangasamy in the field of Microfluidics (Producing drug particles with core-shell morphology for Pharmaceutical applications) industrial colloborative with Dr. Reddy's Lab, Hydrabad

After my PhD, I joined as Post-Doctoral researcher in University of Gothenberg, Sweden with Prof. Dag Hanstorp , Where I working on Microfluidics to study the particle dynamics in low Reynolds number . This project is colloborated with Theortical group Prof. Bernhard Mehlig
