Research Interests
Environmental
biogeochemistry. Physical geochemistry. Surface chemistry.
Investigations incorporate
spectroscopic experiments and theoretical molecular modeling. Recent
research has focused on molecular-level understanding on interactions
of organic compounds and microbial extracellular polymers with natural
particles. Current research project investigates structures
and reactivities of biogenic nanoparticles (e.g., manganese oxides
produced by bacteria) toward photoredox reactions
and metal-scavenging.
