My research is focused on the discovery and understanding of novel electronic, optical and spin effects in low dimensional solid state systems, and their applications to technology. I am currently focused on optoelectronic and spin physics of 2D material semiconductor systems, specifically monolayer transition metal dichalcogenides (TMDCs), and 2D heterostructure devices, where we use the unique properties of disparate materials (TMDC, graphene, hexagonal boron nitride, FeSe, NbSe2, and organic semiconductors) layered together, to study the physics of atomically sharp material junctions.
