Research Statement and Projects

The study of water-rock interactions spans a wide range of disciplines in a variety of geologic environments. I have been working on fundamental and applied problems related to the geochemistry of water-rock interactions for over 15 years. While at Los Alamos National Laboratory I established an experimental hydrothermal laboratory capable of evaluating multiphase (CO2-H2O) fluid-rock reactions in the Earth’s crust. We produced seminal papers on the nature of these interactions in brine aquifers. In 2008 I moved to the University of Wyoming; I have since established a new research group and constructed a new experimental hydrothermal laboratory.  

My research group works on a wide variety of projects regarding the geochemistry of fluid-rock interactions in the shallow to middle crust. My students all strive to work on fundamental problems as a primary focus. We also seek to apply these fundamentals to understanding problems of societal relevance. Our approach is to integrate laboratory, computational, and field techniques to solve scientific problems. Current projects focus on the geochemistry of fluid-rock interactions in the following: 

  1. fresh water aquifers and brine formations, thermal waters and springs, natural CO2 reservoirs, and carbon storage systems. Geochemical insights that we develop are used to expand our understanding of the architecture of crustal basins;

  2. drinking water resources and interactions with energy development (including oil & gas fields and geologic carbon sequestration);

  3. CO2 in geothermal systems; and

  4. unconventional petroleum systems.  A new student in my group would be given the opportunity to expand on one of these areas or define a new direction.

Traditionally we have focused on the mineralogy and inorganic geochemistry of these fluid-rock systems. Much of our work is centered on experimental geochemistry that is grounded in field-related problems; field geochemistry represents a smaller but important and growing proportion of our work. We are currently developing methodologies to add stable isotope geochemistry to our experimental protocols. We are also beginning to look at the organic geochemistry of water-rock systems. My other long-term research interests include contact metamorphism; quartz and carbonate veins and textures; redox equilibria in crustal-scale (deep) aquifers; and mass and energy transfer in the crust.

Our research is synergistic with the many new and ongoing projects at the University of Wyoming. Candidates with a background or interest and aptitude for geochemistry are encouraged to contact me. Candidates familiar with quantitative geochemical analysis and/or experimental geochemistry are especially encouraged to contact me.

Teaching Statement

Important components of my teaching approach are experiential learning; integrated field, laboratory (qualitative and quantitative/analytical), and classroom techniques; and incorporation of active research questions into field trips, laboratory experiments, and problem sets.  Important goals are to develop in students the ability to recognize and articulate significant problems, the solutions to which represent important contributions to science and society, as well as abilities to identify problems, think creatively, and embrace change.  I strive to foster these qualities in students as teacher and mentor in the classroom, the field, and the laboratory.
