I am interested in using isotope signatures, especially tools like clumped isotopes, to resolve the provenance of methane gases. My goal is to combine lab incubation and modeling to understand the mechanism of clumped isotope fractionation in methanogenesis and methane oxidation. My research are mainly in the field of biogeochemistry, stable isotope and clumped isotopes.

Amanda Calhoun '23
Sr. Thesis Student, Earth Sciences
I am a senior interested in microbial biomarker production and its implications for the co-evolution of Earth and life, as well as astrobiology. I am working on a thesis to constrain the origin of the unique archaeal lipid, crenarchaeol, through analyses of lipid distributions and geochemical parameters in Yellowstone hot spring environments.

Research Assistant, Sr. Project, English and Earth Science major.
I am a senior growing halophilic archaeal lipids to see whether their hydrogen isotope ratios can be used as a climate proxy for life billions of years ago both on Earth and wherever else we find evidence of life.
Whitney Thomas '24
Research assistant, Biology Major
co-advised with O. Zhaxybayeva
I am a junior majoring in Biology and minoring in Public Policy with an interest in ecological genetics. Currently, I am researching the influence of temperature on protein expression and clumped isotope fractionation in methanotrophic bacteria.
