In his professional career, Wynn has served as vice president for R&D of Zonge Engineering [http://www.zonge.com] , and in several rotational management positions in the USGS. Theseinclude Chief of the Office of Geochemistry & Geophysics, Chief of the Venezuelan Guayana &Amazonas Exploration Mission (“Jefe del Grupo Asesor”), where he was first author of the first complete geologic map of southern Venezuela, [Citation

Wynn has studied and published on the Wabar craters asteroid impact event in the Empty Quarter of Saudi Arabia, [Citation

Bismarck Sea in February 2005 and off the east coast of South Africa in a large-scale deployment during May - June 2007 [http://www.wassoc.com/experience/experience.shtml] .

He successfully mapped the groundwater of the San Pedro Basin in southern Arizona and northern (Sonora) Mexico in three dimensions [http://www.zonge.com/PDF_Papers/AMT_Inversion_with_AeroMAG.pdf] . He has published over 230 articles, books, and maps in fields as diverse as geophysics, archeology, and astronomy [http://volcanoes.usgs.gov/jwynn/0bibliography.html] . In 2002-2003 he served as president of the Environmental & Engineering Geophysical Society [http://www.eegs.org/] . He has also completed the month-long Federal Executive Institute training for senior Federal managers [http://www.opm.gov/ses/feimdc.asp] .

Wynn holds a 4th degree black belt in Budoshin (Japanese origin) Jujutsu [http://www.americanjujitsuassociation.org/yudansha.htm] [ "Yodan" means 4th Degree orSensei level; BBB means tested by the AJA Black Belt Board.] , and as a community service has taught numerous free self-defense clinics for women in northernVirginia and Vancouver, WA [http://www.vancouverjujitsu.org] . In 1999 Asteroid "9564 Jeffwynn" was named for him by the International Astronomical Union [http://cfa-www.harvard.edu/iau/lists/NumberedMPs005001.html] .
