My research interests lie in the domain of emerging and exploratory devices and technologies. I mainly work in theory and simulations. While the theory of any new or unique device concept or proposal consists of generating an idea blueprint and rigorous mathematical derivations to establish a proof-of-concept, simulation on the other hand, encompass a numerical calculation to validate a theoretical proposal. Our simulations are mainly based on Density matrix of Fock space approach, non-equilibrium Green's function approach, Boltzmann transport approach and the drift-diffusion approach. Some initial level simulation may also consist of the first-principles calculations. In addition, some circuit level simulations would also be involves, if one aims to analyze the performance of proposed devices in circuit-level systems.
