The overall objective of my research program is to understand how and why microorganisms and geological media (rocks, minerals, water) interact and how we can study their mutual interactions to understand a range of biogeochemical processes on Earth and beyond.. My current research is focused on three broad areas: 1) mineral-microbe interactions; 2) life in various extreme environments (saline lakes on Tibetan Plateau, hot springs, and deep continental subsurface) and implications for life on Mars; 3) environmental bioremediation of heavy metals and radionuclides as well as organics such as TCE and BTEX. I employ an umber of geological, mineralogical, geochemical, and microbiological techniques to study these processes including microscopy, spectroscopy, aqueous geochemistry, molecular microbiology and cultivation, and modeling. Most of my research projects are funded by NSF, DOE, DOD, ACS-PRF, and other internal (Miami University) and foreign (international) sources.

Possible thesis/dissertation topics:

Clay mineral - microbe - organic matter interactions.

Microbial remediation of heavy metals Cr, Tc, U, and As.

Biogeochemical cycling of C and N in hot springs.

Degradation of TCE and BTEX coupled with microbial reduction of iron and other oxidants.

Coupled diffusion and reaction processes of TCE: impact on dilute groundwater plume.
