Dr. Sharma’s research bridges the fields of stable Isotope geochemistry, biogeochemistry, and hydrogeochemistry to address a wide variety of issues related to the “Energy-Environment” nexus.
PI: Shikha Sharma, Professor of Geology
My lab group is currently engaged in several DOE, NSF and EPA funded research projects that address a wide variety of issues related to the “Energy-Environment” nexus. The central theme of my research is to develop better understanding of how nano-scale properties and interactions can transform field scale behaviors of geologic systems. We accomplish this by utilizing wide variety of isotopic, geochemical, biomarker, spectroscopic and mineralogical tools.
The current research in our laboratory seeks to answer fundamental research questions related to 1) physico-biogeochemical interactions occurring in deep subsurface systems like unconventional shale reservoirs and CO2 sequestration systems, 2) tracing transport of fluids, gas, and contaminants in anthropogenically disturbed subsurface and surface hydrologic systems and, 3) cycling of C/N/O/S/H in modern and ancient environments.
