John L. Wilson is Professor of Hydrology in the Department of Earth and Environmental Science at the New Mexico Institute of Mining and Technology in Socorro, New Mexico. He has a BS from Georgia Institute of Technology, and MS, CE and PhD degrees from the Massachusetts Institute of Technology. He is a current or former member of many professional society, university and government science advisory panels and committees, including the National Science Foundation’s (NSF) Advisory Committees for Environmental Research and Education, and for Geoscience, the National Research Council’s Committee on Hydrologic Science, and the American Geophysical Union’s (AGU) Committee on Fellows. He is a member of the Board of Directors of the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI), only recently stepping down as Board Chair. A one hundred university member consortium charged with developing scientific programs and infrastructure, CUAHSI is supported by the National Science Foundation. Wilson is a Fellow of AGU and of the Geological Society of America (GSA), a former Darcy Lecturer, and a holder of the O.E. Meinzer Award from GSA. In his own work, which is related mostly to groundwater hydrology, Wilson’s current efforts focus on contaminant source identification, stream-aquifer interaction, including the hyporheic zone, and recharge to mountains. The latter topic has taken him into related fields stretching from geostatistical precipitation estimation, through land surface energy balance modeling, to remote sensing.
