I am a 3rd year graduate student in the Lunar and Planetary Laboratory advised by Dr. Dante Lauretta. My research focuses on the analysis of metal-sulfide minerals in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission. The composition, structure, and distribution of sulfide minerals in these samples can provide important clues to understand the chemical and physical environment on the asteroid’s parent body, such as temperature, oxidation, and fluid activity, therefore providing valuable insight into conditions and processes operating in the early Solar System. I use a suite of instruments in the University of Arizona’s K-ALFAA facility to conduct a coordinated microanalysis procedure for sulfide characterization. During my Space Grant Fellowship, I will continue this research, specifically working on structural analyses of sulfides, in addition to planning a Sample Return Mission Development Workshop aimed at K-12 students. During this workshop, students will learn about the process of developing a sample return mission like OSIRIS-REx, and work to design their own mission by completing background research, preparing a short mission proposal, and creating a sample return capsule using craft materials. I intend for this workshop to provide an opportunity to learn about space exploration and engage with the scientific process in a creative and accessible way, and plan to implement this workshop in collaboration with local Tucson schools by the end of the fellowship period. Outside of research, I enjoy reading, hiking, scrapbooking, exploring Tucson (especially cute coffee shops!), and spending time with my dog, Pluto!
