Current Research

My current research interests are the exotic properties of graphene and two-dimensional systems spanning diverse topics including electronic, thermal and mechanical properties. Among the research problems In recent years I have studied problems such as the snap-through instability of atom-thin membranes over corrugated surfaces, the electromechanics of 2D systems, the ability to engineer in graphene both ultralow as well as ultrahigh thermal conductivities, and last but not the least, the physics of water and ions under confinement.
