Bio:
B.A. in Chemistry from Scripps College, 2019
M.S. in Chemistry from University of Chicago, 2021
Scientific Affiliate at the Field Museum, 2022
Julie is a fourth-year graduate student in the Chemistry Department focusing on experimental physical chemistry. She always loved learning about space and is excited to be able to apply her training as a chemist toward astrophysical topics. She attended undergrad at Scripps College in Claremont, CA during which she worked in the Astrochemistry Lab with Andrew Mattioda at NASA Ames Research Center. Her senior thesis was on the photochemistry and spectroscopy of a large organic molecule in water ice, similar to what could be found on the surface of an interplanetary dust particle. While an undergrad, she also studied abroad in Denmark and did some bioorganic chemistry research at the University of Copenhagen.
Outside of the lab, Julie enjoys exploring Chicago, reading, and playing with her dog, Latte.
Research Interests:
Cosmochemistry, Astrochemistry
Julie likes topics that analyze the physical properties of materials and the physical processes that led to their origin. She enjoys learning about instrumentation and new analytical techniques. Julie is interested in astrochemistry and the implications it has for astrobiology and "the origin of life", and also likes to question how different elements and materials migrated throughout the Universe and what evolution they underwent during that time.
Her Ph.D. dissertation project is the analysis of elemental abundances in Solar Wind returned in the Genesis samples using CHILI to perform high-resolution, laser ablation depth profiling.
