Jeanine is a postdoc affiliated with the Center for Dark Energy Biosphere Investigations Postdoctoral Fellow at Rice University. She uses the natural abundances of molecules with more than one rare isotope substitution to explore how microbial metabolisms contribute to global biogeochemical cycles.
Dan is a postdoc in the group who comes to us from Caltech. His PhD work focused on the use of sulfur isotopes to better understand fluxes within the modern and ancient marine sulfur cycles. At Rice, he is interested in using a combination of lab experiments, geologic data, and modeling to better understand the controls upon primary productivity and organic matter preservation in sediments.
Yi is a PhD student who arrived at Rice in September 2019. She received her undergraduate degree from the University of Southern California. She is interested in better understanding the kinetics of reverse weathering in marine sediments and the role that physical processes (e.g. erosion) play in modifying the preservation of organic matter in sediments.
Will is a PhD student in the group who came to us after finishing his undergraduate degree at the University of North Carolina. At Rice, he is studying the dynamics of riverine solutes, mineral weathering, and hydrologic processes within a tropical catchment in Puerto Rico using concentration-discharge relationships and water isotope ratios.
Debadrita is a PhD student who came to Rice having worked in the oil & gas industry. She is interested in using the geochemistry of foraminifera (especially trace and minor element ratios) to understand changes in seawater chemistry and climate in Earth's past.
Haolin is a PhD student who has been with the group since September 2020. He got his MSc degree in geochemistry from the University of Alberta, working on organic matter burial in the Middle-Upper Devonian Horn River shale, Canada. At Rice, Haolin is interested in studying organic matter accumulation/burial/preservation and related concepts in terrestrial and marine environments.
Trevor was a Master's student in the group who defended his thesis in April 2020. His work focused on the role of various weathering processes in controlling the concentrations of inorganic solutes within Icelandic rivers.
