I am a Ph.D. Candidate in Planetary Sciences at the Lunar and Planetary Laboratory at the University of Arizona under the supervision of Prof. Roger V. Yelle. I am interested broadly in planetary atmospheres, more specifically aeronomy and atmospheric chemistry. My current research is focused on the upper atmosphere of Mars using data from the Neutral Gas and Ion Mass Spectrometer (NGIMS) onboard the NASA Mars Atmosphere and Volatile EvolutioN (MAVEN) mission. I received a Masters of Science in Organic Chemistry from the University of California, Los Angeles under the supervision of Prof. Timothy J. Deming, where I synthesized polypeptides developed as biomolecular materials for, e.g., drug delivery, and a Bachelors of Science in Chemistry from the University of Texas at Dallas, where I synthesized organic polymers for, fabricated, and tested polymer solar cells under the supervision of Prof. John P. Ferraris.

During both localized and global dust storms, water is delivered to the upper atmosphere, where it is ionized and dissociated. MAVEN NGIMS measures some of the products of these ionization and dissociation reactions. The delivery of H2O to the upper atmosphere during dust storms increases the rate of H escape to space.
We derive neutral temperatures from Ar, CO2, and N2 abundances measured by MAVEN NGIMS over 1.5 Martian years. The temperature profiles cover an altitude range of 150 to roughly 300 km on nominal orbits. During Deep Dips, temperature profiles extend down to about 125 km, near the mesopause. We characterize thermospheric gradients and exospheric temperatures. The thermal structure of the Martian upper atmosphere is important for quantifying loss of the atmosphere to space.
Upcoming and past talks and posters.
I will present a poster entitled, "Transport of Water to the Martian Upper Atmosphere amid Regional and Global Dust Storms" in the Dust - Storms, Grains, Impact on Environment session at the Ninth International Conference on Mars in Pasadena, California.
I gave a talk on the transport of water to the upper atmosphere of Mars during dust storms in the Processes in the Present-Day Atmosphere of Mars II at the American Geophysical Union Fall Meeting in Washington, D.C.
At the 2018 Lunar and Planetary Laboratory Conference in Tucson, Arizona, I gave an invited talk on the Martian global dust storm of 2018 and its impact on the upper atmosphere as observed by MAVEN NGIMS.
At the 52nd ESLAB Symposium on Comparative Aeronomy and Plasma Environment of Terrestrial Planets in Noordwijk, The Netherlands, I presented on measurements of protonated ions from MAVEN NGIMS and the variation of H2 in the Martian upper atmosphere.
I presented on the thermal structure of the Martian upper atmosphere as observed by MAVEN NGIMS at the International Conference on Mars Aeronomy in Boulder, Colorado.
