Professional Background

Dr. Hanson received a B.S. in Nursing from Montana State University in 1979. After working as an Operating Room nurse for several years, he returned to school at San Diego State University and completed undergraduate classes in geology and continued on to receive an M.S. in Geoscience in 1993. He continued his education at Stanford University and received a Ph.D. in Geology in 1999. Internships with Mobil Producing in Bakersfield, CA and with Texaco in Houston, TX led to full-time employment after graduation with Texaco's International Exploration Division where he was a geoscientist with the Nigeria Exploration team. Andrew joined the faculty at UNLV in August of 2000. He is a member of the American Association of Petroleum Geologists, the Geological Society of America, and the Society of Sedimentary Geology.

Research

Sedimentary basins and the petroleum resources they contain are the primary focus of the research that my students and I conduct. Our work is strongly field-based but incorporates both outcrop and subsurface data (seismic and borehole) and is combined with cutting edge lab analyses. Tools used in our research include geologic mapping, facies interpretation, paleocurrent analysis, sedimentary petrography, molecular organic geochemistry, basin modeling, detrital zircon analyses, apatite-fission track analysis, U/Th-He analysis, Ar/Ar geochronology, tephrochronology, and architectural element analysis. Currently my students and I are working on projects focused on Miocene-Pliocene extensional basins in the southwestern United States, Cretaceous to Eocene synconvergent extension in the Sevier hinterland, and hydrocarbon migration and maturation in La Popa basin, northeastern Mexico.
