From 1994 to 1996, he was a Research Professor with the Earth Sciences and Resource Institute at the University of Utah.

Deet has a longstanding interest in the exploration and development applications of petroleum geochemistry, particularly surface exploration methods. He is editor, with Mike Abrams, of the recently published AAPG Memoir 66, Hydrocarbon Migration and Its Near-Surface Expression. He and Len LeSchack are now working on a follow-up volume for AAPG, Surface Exploration Case Histories. Deet is a Certified Petroleum Geologist (CPG-4301), a member of AAPG and GSA, and a past president of the Houston Geological Society.
