Research Group / Current & Alumni

Overview

My group —students at all levels, post-docs, and visiting scholars—has always had a broad mix of people, interests, activities, and goals. Undergraduates are involved in work-study and independent research projects; graduate students and post-docs tackle diverse topics, typically with independent funding. We also work with closely with many in the Department, particularly with Eric Seedorff's group, but also with others in the Mineral Resources, Petrology, Geochemistry and Tectonics groups. We also work closely with geologists from a number of mining companies and from the U.S. Geological Survey.

Like my research interests, thesis and undegraduate research topics have been diverse. Theses have spanned economic geology to experimental petrology to isotope geochemistry to structural geology to mineralogy. Over the years, MS and PhD graduates, and former post-docs have gone on to a wide variety of careers that draw on their training in geosciences. A primary goal of mine is to challenge everyone in our group to find something that excites them, to pursue it to completion, to develop tehnical expertise, to improve communication skills, and—ultimately—to build on that experience in another setting, be it in a career or further education.

Academic careers:  Graduate students and post-docs have gone on into university careers in geology and related fields include: Denise Battles (PhD; Prof. of Geology & Dean College of Natural and Health Sciences, University of Northern Colorado), Gray Bebout (PhD; Prof. Geochemisty, Lehigh Univ.), Kurt Friehauf (post-doc; Assoc. Prof., Kutztown Univ.), Jamshid Hassanzadeh (PhD; Prof. Geology, Teheran Univ.), Lynn Ingram (MS [Stanford PhD]; Assoc. Prof. Geography, U. California, Berkeley), Robert Marschik (post-doc; Prof. Econ. Geology, Ludwig-Maximillians Univ., Munich), and Ntsiki Van Averbeke (MS; Ft. Hare College). Several other students have gone into teaching high school science (Jim Gonzalez, Greg Ghidotti).

Other former graduate students who are still in the academic mill include Julie Hamblock (MS; now PhD candidate, UTEP), Eric Jensen (PhD; now post-doc, Univ. Arizona), and David Johnson (PhD; now post-doc, Univ. Arizona). The majority of the 40+ undergraduates who have worked with our group over the years have gone on to graduate school.

Mining and petroleum industry related careers:  Students who have gone on into successful careers in related to the mining and petroleum industry include: Ron Bertasi (MS [MBA, Dartmouth], President, Southern Company Energy Solutions), Carlotta Chernoff (PhD; Geologist, ConocoPhillips), Adam Graf (MS [MBA, U. Arizona]; Mining Industry Analyst, BearStearns), Martin Herrmann (MS; Geologist, ExxonMobil), Bob Ilchik (PhD, Senior Exploration Geologist, Sino Gold), John-Mark Staude (PhD; Global Assessment Leader-Advanced Projects, BHP-Billiton), and Wojtek Wodzicki (MS & PhD; General Manager Exploration, North America, Teck-Cominco). Eric Jensen (PhD) and David Johnson (PhD) have founded and run their own exploration company in addition to their continuing instructional involvement through our short courses.

Government and environment related careers:  Among my students who have gone on into careers in geology are: Serigo Castro-Reino (PhD; Research Geologist, Desert Archaeology), Sean Doherty (MS; President, ERM Southwest Inc.), Frank Mazdab (PhD, Staff Mineralogist, U.S. Geological Survey), Mark Rollog (MS, Staff Isotope Geochemist, Univ. Arizona), Dave Szumigala (PhD, Senior Econ. Geologist, Alaska Dept. of Natural Resources), and Heather Trim (PhD; People for the Puget Sound, formerly Staff Scientist for Los AngelesWatershed Council).
