I am a Project Scientist at the Berkeley Center for Cosmological Physics and a Data Science Fellow at the Berkeley Institute for Data Science at UC Berkeley.

In part of my job, I study cosmology using Type Ia supernovae as part of the Nearby Supernova Factory, an experiment designed to study nearby Type Ia supernovae in depth in order to enhance their use for cosmology. In the other part of my job, I write and maintain open-source scientific software (primarily for astronomy research) and investigate ways to make it easier for scientists to use programming tools to accomplish their research.

Previously, I was a postdoc at Argonne National Lab, in the High Energy Physics division. I did my PhD at UC Berkeley with Saul Perlmutter as part of the Supernova Cosmology Project.

Very occasionally, I write up some of my explorations in open-source scientific software in the blog section of this site.
