About Me

I am a geochemistry postdoc at Caltech. I work on problems in mass spectrometry, noble gas geochemistry, geochronometry, and thermochronometry. From 2005 to 2009, I was an undergraduate at Columbia University in the City of New York, where I worked in Sidney Hemming's AGES Argon Geochronology Lab.  I worked full-time as a research assistant in the same lab from 2009-2010 before coming to Caltech in 2010. I was a graduate student from October 2010 to December 2016, and I am now a postdoctoral research scientist.

My research interests include geochronology and thermochronology, palaeoclimate, and surface processes.  As an undergraduate, I conducted research on erosion rates in East Antarctica using detrital thermochronology.  I am currently working on projects involving the development of (U-Th)/Ne, U-Kr, and U-Xr dating techniques. I have characterized the production rate of neon from alpha particles in all materials and I have studied the diffusion of neon from several minerals. I am also working on the development of a static vacuum quadrupole ion trap mass spectrometer for terrestrial and extraterrestrial geochronology with Stojan Madzunkov, Murray Darrach, Dragan Nikolic, and Rembrandt Schaefer at JPL.
