Research focus (graphene-related):
Graphene in structured electromagnetic materials, tunable graphene metamaterials, graphene plasmonics, nonlinear optics of graphene.Theoretical methods: Finite-element method (FEM), finite-difference time-domain method (FDTD), and effective-circuit models for the quantitative modeling of nanophotonic structures; linear response theory for the conductivity of graphene; semiconductor Bloch equations for the nonlinear response of graphene.
Focus of future research (graphene-related):
•    Nonlocal response of graphene and its impact on dissipative loss of graphene plasmons;
•    Graphene-based refractive index sensors;
•    Tunable and time-dependent terahertz metamaterials;
•    Surface plasmons on non-equilibrium graphene.
