Educational Background

  • Ph.D., 1998, University of Cincinnati
  • M.S., 1994, Wright State University

Research Interests

Stable isotopes in sedimentary environments (past and present) and their application to sedimentary ore deposits.

The fate of metals in the environment, and in the development of tropical soils.

Low temperature hydrothermal rock-water interactions at oceanic spreading ridges

The influences and interactions with microbial activity and microbial byproducts with these rock-water interactions.

Teaching Philosophy

Students learn by doing and by dialog. Students in my laboratory and classes are exposed to a wide variety of geologic materials and problems, and are encouraged to engage in dialog to discuss and write about their findings in order to develop critical thinking skills along with a deeper understanding of the geologic concepts, materials, and systems.

Recent Research Projects

Analysis of copiapite samples from Devonian black shale outcrops.

Sulfur Isotopic Budget of the Yaxcopoil-1 Core, Chicxulub Impact Crater and modeling of the sulfur isotopic fractionation at the K/T boundary.
