Behavior of dense fluid-particulate systems; particle agglomerations; rock behavior of deep geo-reservoirs; hydraulic fracture intitation and propagation in rock mass; re-fracturing and hydro-thermo-mechanical coupled processes in fractured rock mass; proppant flow and transport in geo-reservoirs; induced seismicity and CO2 sequestration.
Tomac’s research focuses on exploring and building the civil engineering infrastructure to support renewable and sustainable energy resources. Her research interests revolve around soil and rock mechanics, hydraulic fracturing, geo-reservoirs and carbon dioxide sequestration. She is actively involved in geotechnical engineering practices in Europe and the United States.
Tomac joined UC San Diego after earning a Ph.D. in civil engineering at the Colorado School of Mines in 2014. She earned her master's in geotechnical engineering at the University of Zagreb in 2007. She is a board member of the Geotechnical Testing Journal.
