Faculty Overview
Dr. Hawkins’ primary teaching and research interests are in heat and reactive mass transfer in Earth’s subsurface, particularly in the context of “next-generation” tracer technologies. Research projects have largely focused on geothermal reservoir engineering with additional applications in nuclear waste disposal, groundwater remediation, carbon sequestration, and subsurface energy storage. Novel tracers that he studies include engineered nanoparticles, reactive tracers for temperature and area reporting, DNA/microbial tracers, and “active” tracers for controlling subsurface fluid flow paths.
