Born and raised in southern California, Jeff’s first introduction to the science of geology came from his grandfather’s extensive mineral collection and vivid stories of work in the mines of Aspen Colorado. From this informal beginning, Jeff earned degrees in geology from the University of Southern California (B.S.) and the University of Arizona (M.S.) where he focused on tectonics and structural geology. He has worked as a petroleum geologist, and as an engineering geologist engaged in landslide and earthquake-hazard mitigation. Jeff has worked as a shipboard naturalist with Lindblad Expeditions since 2002.
For over thirty-five years, Jeff has taught geology and physical science at Cuesta College in San Luis Obispo, California. Focusing on introductory courses in California Geology, Physical and Historical Geology, he has also organized and led numerous field seminars to Yosemite, the eastern Sierra Nevada, Death Valley, and the Grand Canyon. He was awarded the “Peter and M ’May Diffley award for Faculty excellence in 2016. Jeff has also worked as a volunteer ranger in Grand Canyon National Park and volunteers as a guest speaker-field trip leader for community environmental groups. An avid surfer, Jeff has surfed and explored the South Pacific, Asia, Europe, Iceland, Mexico, Central America, and Alaska. He enjoys reading, gardening, cooking and social dance. He is married and has three children: daughter Ashlyn, and stepsons Michael, and Joey.
