Research 

First-principles computational methods of extended systems for a microscopic understanding of optical, electronic, and transport properties in energy sustainability technologies.

Computational Engineering of Optoelectric Materials

Our group utilizes and deploys computational methods to engineer the optical, electronic, and transport properties of materials in energy sustainability technologies. Enabled by high performance computing (HPC), we seek to elucidate and predict the materials properties at the microscopic level using first-principles calculations, drive the exploration of novel materials platforms, and create strategies that directly couple to experiments. In particular, we look to understand and harness defects in materials for optoelectronic devices. Research in the group is highly interdisciplinary and draws upon fields such as chemical engineering, materials science, and solid-state physics.

Current research goals are focused on catalysis, energy conversion, and next-generation computing applications.


Throughout our research and teaching efforts, we strive to create and foster a diverse, equitable, and inclusive environment.
