Research focus:
Electronic structure theory of nanostructured systems including two-dimensional materials and van der Waals heterostructures (GRMs). Parameter-free theoretical characterizations and predictions of their interactions with molecules, fields, and with materials.
Theoretical methods:
Strictly parameter-free, nonlocal formulations of density-functional theory anchored in many-body physics. We develop and leverage modern exchange-correlation functionals that systematically describe dispersion or vdW forces as they act in concept with other materials interactions.

Focus of future research:
  • Nature and engineering of binding in van der Waals heterostructures
  • Doping, and charge-transfer effects in graphene multilayers
  • Anchoring of functional groups; characterizations of charge and neutral excitations.

Highlights of previous research:
Formulation of the general-purpose van der Waals density functional method; consistent handling of spin & exchange effects, and hybrid corrections.
