Reza Soltanian

Reza Soltanian is an Associate Professor of Hydrogeology in the Department of Geology at the University of Cincinnati. His research focuses on subsurface fluid flow, reactive transport, and multiphase flow in porous media, with applications to carbon sequestration, contaminant fate, and ecohydrology. He holds a PhD in Earth and Environmental Sciences from Wright State University (2015), preceded by an M.Sc. from the University of Tehran (2010) and a B.S. from the University of Shiraz (2008).

Dr. Soltanian has held roles such as Subsurface Modeling Lead at Subsurface Insights, LLC and Civil Inspector at DAELIM Industrial Company. His work bridges theory, numerical simulations, and field-scale approaches to address critical environmental challenges. Current active grants include Department of the Army funding for monitoring subsurface biogeochemical hot spots (Role: PI) and American Chemical Society support for methane emissions modeling (Role: PI).

His research interests emphasize geologic CO₂ sequestration, multiphase fluid dynamics, and the impacts of heterogeneity on subsurface processes. Notable projects include studies on gravitational instabilities in carbon storage and hyporheic exchange dynamics in karstic streams.
