Shikha Sharma

Marshall S. Miller Energy Professor of Geology

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.

IsoBioGem Lab

PI: Shikha Sharma, Professor of Geology


Research in my IsoBioGeM laboratory focuses on Environment and Sustainable Energy Solutions related to unconventional shales, subsurface CO2 and H2 storage, geothermal systems, and critical and rare earth mineral extraction. We employ diverse isotopic, geochemical, microscopic, spectroscopic, mineralogical, and biological techniques to investigate these research inquiries. We have led several multi-institutional collaborative research projects funded by the Department of Energy (DOE) - Geothermal Technology Office, DOE - Office of Basic Science, DOE - Office of Energy Efficiency & Renewable Energy, DOE-National Energy Technology Laboratory, National Science Foundation, Environmental Protection Agency, USGS and US Department of State.
