His interest in transport at semiconductor interfaces has resulted in significant contributions to advances in organic optoelectronic devices, as well as emerging next-generation photoconversion technologies. Understanding semiconductor structure and its relationship to optoelectronic properties at heterointerfaces is an ongoing theme of his work throughout his scientific carrier. These interests in fundamental aspects of interfaces have also led to ongoing internal and external collaborations to develop solution-processed materials systems, and closely related efforts on high-throughput approaches to material and device development.
