Curriculum Vitae

Biography

Matthew Reagan is a Staff Scientist in the Energy Geosciences Division (EGD) at Lawrence Berkeley National Laboratory. He specializes in research on the thermodynamics, transport, and chemistry of aqueous and hydrocarbon systems in the subsurface, including research on shale gas and shale oil reservoir simulation and engineering, thermodynamics of gas hydrates, methane hydrates as a resource, data reduction and uncertainty, the coupling of methane hydrates and global climate, and the impacts of oil and gas production on the environment.

Research Interests

Fundamental and applied research on the thermodynamics, transport, and chemistry subsurface systems, including:
Developer for the TOUGH family of numerical simulation codes, programming libraries, and public-facing tools for physical property estimation
Authored or co-authored 58 peer-reviewed papers, two regulatory studies, and 44 articles and reports
Gave over 55 technical presentations, including 7 invited talks
