David Williams, Lab PI
Dave is a plant physiological ecologist by training and enjoys working on problems in hydrology and biogeochemistry. He earned his BS at the University of Texas at Austin, MS at Texas A&M University, and PhD at Washington State University. He joined the faculty at the University of Wyoming in 2003 after serving on the faculty at the University of Arizona for 8 years. He is the faculty director of the University of Wyoming Stable Isotope Facility.
Felix Bredoire, postdoctoral researcher
Félix studies terrestrial biogeochemistry in natural ecosystems using tools such as stable and isotopes and modeling. He enjoys outdoor sampling adventures, international collaborations, multidisciplinary approaches, and thinking at different spatial and temporal scales. Félix got a PhD in functional ecology at the University of Bordeaux, France, while studying the influence of climate change on biogeochemical cycles in Siberia, Russia. He then moved to Nancy, France, for a postdoc where he worked on the link between soil biogeochemistry and forest fertility. Now, at the Williams lab, Félix is focusing on the microbial aspects of biogeochemistry, taking advantage of some exciting environmental gradients that exist in Wyoming.
William Bowers, PhD student
I attended Colorado College for my undergraduate degree in Biochemistry and a minor in Studio Art. I have always been an outdoors enthusiast which is why I am pursuing higher education to better understand the natural word that I love to explore. I am currently pursuing a PhD in the Interdisciplinary program of Water Resources/ Environmental Sciences and Engineering at the University of Wyoming. My research focuses on water cycling in the vadose zone and the relationship it has with nutrient cycling, transport, and bioavailability.
Abigail Hoffman, PhD student
As a PhD student in the Program in Ecology, Abby studies nitrogen cycling in seasonal and perennial snow throughout Wyoming with an emphasis on understanding microbial assemblages and processes during snow melt. She earned her MS in botany at the University of Wyoming studying patterns and sources of atmospheric nitrogen deposition in the Greater Yellowstone Area using lichens and ion exchange resin collectors. She earned her BS at Duke University. She enjoys using a broad range of methods from DNA sequencing to stable isotopes and modeling to answer questions about microbial processes and nutrient cycling at different spatial and temporal scales.
Jason Mercer, PhD student
I am currently a PhD candidate in the Hydrological Sciences program and Department of Botany at the University of Wyoming. My research is loosely organized around the fields of hydrology, ecology, and soil physics with a particular emphasis on mountain wetlands, lakes, and streams. Common tools I use to address my research interests include stable water isotopes, near-surface geophysics (e.g., GPR, NMR), process-based modeling (with an emphasis on Bayesian techniques), and remote sensing (e.g., structure from motion). I’m a big advocate of open science, and thus this site focuses a lot on those aspects of my work.
