William Roggenthen

Bill Roggenthen is a Research Scientist with the Dept. of Geology and Geological Engineering (GGE) at the South Dakota School of Mines (SDSMT).  He received his B.S. in Geological Engineering at SDSMT, an M.S. in Geology at the University of Colorado, and his Ph.D. from Princeton University.  From 1985-1995 he was the head of the GGE Department at SDSMT and the Dean of the College of Earth Systems from 2002 to 2004, as well as being a Professor in that department.  Two years were spent with the U.S. Dept. of State in 1995-1996 and in 2000-2001 working on nuclear issues. He has ongoing research in the fields of environmental and engineering geophysics, and his work in the underground began at the Waste Isolation Pilot Plant (WIPP) site in southeastern New Mexico in 1988-1992. Work at the WIPP site included investigations of local brine inflow into the salt excavations and rock stability in support of planning for that site.  He was the co-PI for the DUSEL Project during the early stages of SURF and later was a member of the kISMET collaboration that characterized the state of stress of rock exposed on the 4850 Level of SURF. He is associated now with the currently active EGS Collab project that had experiments on the 4850 Level and that is now creating laboratory space and developing experiments on the 4100 Level.
