Research Statement

We advance and deploy ever-increased understanding of materials chemistry and the physical chemistry of materials and surfaces towards three missions:
  1. Capturing and utilizing CO2 in order to make efficient CO2-recycling fuels and CO2-sequestering materials.
  2. Advancing the performance and the underlying science of high-efficiency solar cells, including perovskite tandem solar cells.
  3. Developing sensors, such as for the UV and infrared wavelengths, that exceed in performance that of existing photodetecting materials and devices.

We rely on computational materials science and computational chemistry; AI/ML; the inorganic and hybrid organic-inorganic materials synthesis, physical chemistry, as well as applied physics, in the pursuit of these goals.
