Steven Ingebritsen, Ph.D.
Research topics include magmatic-hydrothermal systems, crustal permeability, and land subsidence
Served a 10-year term as a USGS Branch Chief (1998-2008), managing a $19M/year research program with about 150 full- and part-time employees and contractors. Fellow of both the American Geophysical Union and the Geological Society of America (GSA); recipient of the O.E. Meinzer Award from GSA and the John Hem Award from the National Ground Water Association; and a GSA Birdsall-Dreiss Distinguished Lecturer. Author of the textbook Groundwater in Geologic Processes (Cambridge University Press, 1998, 2nd ed. 2006) and co-Editor of Crustal Permeability (Wiley/AGU, 2016). Past co-Editor-in-Chief of Geothermics (1996-1998) and Geofluids (2006-2010) and past Chair of GSA’s Hydrogeology Division. Member U.S. National Academy of Engineering.
