B.S.: Environmental Chemistry (WSU, 1999)

     - This degree focused on interdisciplinary studies, including mircobiology, inorganic chemistry, organic chemistry, environmental science, and natural resource management.

Masters: Geology, Emphasis in Groundwater Studies (WSU, 2002)

     - My thesis described the reaction of the nutrient pools in a controlled sandbox

       red pine stand to a simulated clear-cut of all the trees, but without any further disturbance of the soil or litter layer.


It's hard to collect microbial biofilms without spooking them...

Research interests:

  • My current Dissertation Research is focused on microbial biofilms found in selected hotsprings in Yellowstone National Park.
  •    I am looking at the major and trace element compositions, C-13 and N-15 signatures, and C-13 fractionation
  •    of biofilms found over a wide range of temperature (30 to 94 C) and pH (<1 to >9). I have collected samples
  •    starting in 2003, and continuing through 2007. Samples I collect include water, biofilms, silica precipitate,
  •    and contextual samples (such as soil, parent rock, etc.).
  •    Estimated date of Graduation: 2008
