Brian Davis started caving in 1988 after meeting Larry Bean during a rock climbing trip. During his childhood he read "The Longest Cave" and similar books, thinking that grand exploration of that caliber was a thing of the past. Then he was introduced to Fisher Ridge Cave System and the Detroit Urban Grotto, and quickly became hooked. On his third trip into the cave he helped discover and map Grand Avenue, a 40' wide trunk passage that had been suspected but eluded explorers for several years. He has been an active member of the project for ten years, and has contributed to basecamp trips as well as many shorter 20-24 hours trips. He has the dubious distinction of being one of only two people to every be trapped in the cave twice, after which he stopped basecamping and put his full effort behind the excavation of a new entrance (the Quick Exit) to prevent further occurrences. Discovery credits include several large trunks or trunk segments in the Northtown section of the cave, including Giant's Pass & KN Kanyon, as well as several discoveries in the more historic (first 50 miles) of cave including pushing leads in Ice Cave Ave, on the far side of the Chocolate Icehole.

Brian lives in Monticello, Illinois, about 20 minutes west of Champaign/Urbana, with his wife Laura Munkel, his one-year-old son Benjamin, and Meg the cat. He graduated from the University of Michigan in May of 1998 with a Ph.D. in Physics, with his research concentrating on stable isotopes of oxygen and hydrogen in surface waters (one method of inferring past climates). His interests include cave hydrology and speleogenesis, planetary science, climate, physics, rock climbing, backpacking, and playing with his son. He is currently a stay-at-home dad and loving it.

Currently he is interested in studying some of the more technical aspects of the cave, including how the cave responds to barometric and temperature changes, and the detailed history of various passages. Mapping is central to these interests, and remains one of his primary focuses.
