Terahertz conductivity in 2D materials:
We investigate the effect of different scattering mechanisms in terahertz transport in 2D materials, especially transition metal dichalcogenides (TMDs) using our in-house multiphysics tool combining ensemble monte carlo (EMC) and Finite-difference time-domain (FDTD) technique.

Nonlinear optical enhancement using plasmons:
We theoretically demonstrate the increase of nonlinear optical properties in graphene by patterning with anti-dots to induce plasmonic resonance.
