Jeff Wynn, PhD

Research geophysicist working on electrical imaging of volcanoes; mineral resource assessments in Central Asia, Venezuela, and Saudi Arabia; geologic mapping in Venezuela and Mexico; airborne 3D groundwater mapping; patents on oil pollution tracking in the deep ocean, below the seafloor, and river bottom Superfund sites; geophysical archaeological prospection, and asteroid impact physics.

Jeff Wynn has served as vice president for R&D of Zonge International, and in several rotational management positions in the USGS. These include Chief of the Office of Geochemistry & Geophysics, Chief of the Venezuelan Guayana & Amazonas Exploration Mission ("Jefe del Grupo Asesor"), where he was a U.S. State Department diplomat and first author of the first complete geologic map of southern Venezuela, and co-published the first full mineral resource assessment for the roadless southern half of Venezuela. Wynn also served for four years as the Deputy Chief for Science and Chief of the USGS Saudi Arabian Mission, before becoming the Chief Scientist for Volcano Hazards in the USGS. He has taught as an adjunct professor of geophysics at the University of Maryland and The George Washington University. In 2002-2003 he served as the President of the Environmental & Engineering Geophysical Society, and has been awarded three patents (a 4th pending) on ocean geophysics and Superfund site pollution mapping. He developed and published a technology to map groundwater in three dimensions from the air, and earned a DOI Meritorious Service Award for science and diplomatic leadership in Venezuela. In 1998 the International Astronomical Union named a Mars-crossing Phocaea asteroid "9564 Jeffwynn" for him.
