Leishangthem Premkumar

I am an Assistant Professor in the Department of Physics at Manipur University, India. My research focuses on soft matter and active matter, with particular emphasis on liquid-glass transitions and the collective behaviour of self-propelled systems studied through theoretical modelling and computer simulations.
