Prior to this appointment, she worked at the Jet Propulsion Laboratory, California Institute of Technology. Her Ph.D. work was with Richard Mathies at UC Berkeley after she earned a Master’s degree in Chemistry from Brown University and a Bachelor’s degree in Aerospace Engineering and Chemistry from the Massachusetts Institute of Technology. Dr. Stockton has extensive experience in the use of microcapillary electrophoresis, laser-induced fluorescence (µCE-LIF) to detect exceptionally low levels (sub-pptr) of organic molecules in astrobiologically relevant samples, including those from the Murchison meteorite, Atacama Desert, Saline Valley, Rio Tinto, etc… Her work also includes a significant field-work component, including the FELDSPAR project involving repeated expeditions to volcanic regions of Iceland as a Martian analog study.
