Field of Specialization: Near-Surface Geophysics

Lee Slater, Distinguished Professor and Henry Rutgers Professor in Geophysics at Rutgers University Newark, is an internationally recognized expert in near surface geophysics and hydrogeophysics. He has published extensively, including 165 papers in peer reviewed international journals of hydrogeology and geophysics. Lee has served as principal investigator on multiple research and technology demonstration projects funded by the US Department of Defense, US Department of Energy, US Department of Agriculture, US National Parks Service and National Science Foundation. He has also served in prominent leadership roles in the academic geophysical community, including Chair of the Near Surface Geophysics Focus Group of the American Geophysical Union (AGU), Chair of the AGU Hydrogeophysics Technical Committee and President of the Environmental and Engineering Geophysical Society (EEGS). Lee currently serves as Associate Editor of Water Resources Research (WRR) and he recently coauthored a new advanced-level text on the resistivity and induced polarization methods applied to studies of the near surface Earth. Lee has served on multiple advisory boards for large interdisciplinary hydrogeological research projects in Europe. He was the recipient of the 2013 Harold B. Mooney award of the Society of Exploration Geophysicists (SEG). His numerous PhD graduates have mostly gone onto academic positions and are now making their own contributions to advancing research in hydrogeophysics.  In 2018 Lee was elected Fellow of the American Geophysical Union (AGU), with the citation: "for visionary experimentation in near surface geophysics that has advanced understanding of subsurface hydrogeological and biogeochemical processes".
