I am a doctoral student who is interested in using uranium-lead geochronology to better time the durations and tempos of Earth processes. While an undergraduate in Blair Schoene's laboratory at Princeton University, I sought to understand how rare Earth elements and hafnium isotopes could reveal the provenance of zircons that had been used to date the eruption of the Deccan Traps. Now as a member of Mauricio Ibañez-Mejia's group, I have focused my studies on improving methodologies in uranium-lead dating. My research is divided into two areas. The first involves further developing uranium-lead dating for baddeleyite, a mineral commonly found in mafic rocks. The second aims to correct sedimentological biases in detrital zircon data using samples from the Río Bermejo in northern Argentina. My Ph.D. minor is in French, and I have previously studied Spanish.

Hailing from the great state of Delaware, I enjoy hiking, photography, and sporting clays in my free time.
