To Potential Students and Postdocs

If you are curious about the role of water in regulating global environmental change, physically, chemically or biologically, in the distant or recent geologic past, or in the present and the near future, please contact me and we'll chat. I am a hydrologist not interested in water per se, but in what water does to shape our landscape through the ages. Water connects all. Little happens without water. At least on this planet. 

Courses I Teach

  • Undergraduate: Hydrogeology (01:460:428:01), offered in the Fall in odd years (2017, 2019, ...)

  • Undergraduate: Hydrologic Processes (01:460:414:01; 11:670:414:01), offered every Spring

  • Undergrad/Grad: Major Events in Earth History (01:460:480; 16:460:580), one lecture on "The Devonian and the Rise of Plants"

  • Graduate: Groundwater Modeling (16:460:528:01), offered in the Fall in even years (2018, 2020, ...)

  • Graduate: Seminar in Hydrology (16:460:632), offered as needed    

Research Interests

  • Water-plant relations belowground, present, past, and future

  • Co-evolution of land plants and the terrestrial environment

  • Global environmental change
