Principal Research Interests

We approach solid-state materials using the tools of synthetic molecular chemistry and design hybrids to combine the strengths of molecules and extended solids. We target materials for applications in renewable energy and pollution management: sorbents for environmental pollutants, phosphors for solid-state lighting, electrodes for secondary batteries, absorbers for solar cells, etc. We also design molecular centers for the electro- and photo-catalytic activation of small molecules relevant to clean-energy cycles. Exploration is at the forefront of our research efforts and we often work with researchers in other disciplines to drive the discovery of new materials.
