Lokesh Malik

I am a PMRF Ph. D. scholar working in the area of Acoustofluidics with Ashis Research Group under the supervision of Prof. Ashis Kumar Sen at the dept. of Mech. Engg., IIT Madras, Chennai.

My research focus is on acoustic trapping of particles and drops in microfluidic systems exposed to bulk acoustic standing waves. You can find my updated CV here.
