My research interests lie broadly in the area of semiconductor device physics. Specifically, my focus is on modeling and simulation of electronic transport in nanoscale transistors and quantum mechanics of open systems that are out of equilibrium. Over the past years, I have, through the non-equilibrium Green's function (NEGF) formalism, been investigating the opportunities and challenges involved in leveraging band-to-band tunneling phenomenon and layered material systems for next-generation low-power devices.
My CV can be found here.
