I am a postdoctoral fellow working with Dr. Dominique Weis towards optimizing the analyses of non-traditional stable isotopes using a multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS). In particular, Fe is an abundant element within the Earth’s crust and the accurate measurement of the isotopic composition of various reservoirs can elucidate geochemical processes in both high- and low- temperature geochemistry. However, interferences during sample uptake severely limit the applicability of the isotope system. For this research, I will be collaborating with Nu Instruments to determine whether sample precision can be improved using a new collision cell MC-ICP-MS. My prior work focuses on the mechanisms that fractionate molybdenum (Mo) isotopes during low-temperature biogeochemical cycling (Ph.D., Oregon State University, 2017).
