Extensive experience in the experimental and theoretical optoelectronic properties of III-V semiconductors, superlattices, nanostructures and related devices. In particular, our recent work is focused on optoelectronic devices such as multi-color detectors, near-, mid-, and long-wavelength infrared detectors. Other research areas include III-nitrides for many electronic and optoelectronic applications; photovoltaic materials and devices; and growth of nanomaterials.
