Artificial Photosynthesis
Electron- and Photo-Induced Processes for Molecular Energy Conversion

Research Interests

Fundamental radiation chemistry of organic liquids, including the development of new radical scavengers. Photochemistry and radiation chemistry of transition metal complexes and other systems in conventional solvents, supercritical fluids, and ionic liquids, to gain a fundamental understanding of processes in solar fuels production and catalysis, e.g., CO2 reduction, H2 production, and small molecule activation. Development of advanced, nanosecond time-resolved infrared (TRIR) detection methods for pulse radiolysis and laser flash photolysis, and their use in mechanistic investigations of catalytic and other processes. Transient spectroscopic techniques (UV-visible and time-resolved infrared (TRIR)) on fast and ultrafast timescales.
