Faculty and Staff

Listed here are brief biographies of the PRC directors, the PRC support staff, and the individuals within UMD's Department of Geological Sciences and Natural Resources Research Institute who principally constitute the PRC Working Group (see organizational diagram). The role of the working group is to offer advice and recommendations on the various PRC activities and programs on a semi-regular basis.   The PRC also will consult with its Board of Advisors on an annual basis. In addition to these individuals, various professional and academic geologists who contract with on various PRC programs (e.g., field camp, workshops, outreach activities) are listed as affilated staff.

PRC Directors: Jim Miller, Dean Peterson, George Hudak
PRC Support Staff: Marsha Patelke, Denise Endicott, Julie Heinz
PRC Working Group: Don Fosnacht, Howard Mooers, Mark Severson, Nigel Wattrus, Christian Schardt

Field Experience: Over the past 20 years, I have gained broad experience in geological mapping of rocks of all types, ages, and locations mainly through my work with the mineral exploration industry in search of mesothermal-gold, epithermal-gold, volcanogenic massive sulfide, copper-nickel-PGE in the Duluth Complex, high-grade copper-PGE veins beneath the Sudbury Igneous Complex, and copper-gold-molybdenum porphyry deposits.

Research Interests: Economic geology, geological mapping, Precambrian geology, mineral potential modeling, and three-dimensional modeling of ore systems. I have broad experience in geological mapping of rocks of all types, ages, and locations mainly through my work with the mineral exploration industry in search of mesothermal-gold, epithermal-gold, volcanogenic massive sulfide, copper-nickel-PGE in the Duluth Complex, high-grade copper-PGE veins beneath the Sudbury Igneous Complex, and copper-gold-molybdenum porphyry deposits.
