Hello! I'm a data scientist at The Climate Corporation, where I'm using weather and agronomic data to build predictive models of crop diseases. I spend my time doing a little machine learning, a fair bit of statistics, and a lot of thinking about potential bias.
Before joining The Climate Corporation, I got a PhD in physics from UC Berkeley in 2011, where I studied supernova cosmology under Saul Perlmutter. I was later a Director's Fellow at Argonne National Lab, a Data Science Fellow at the Berkeley Institute for Data Science (BIDS), and most recently a Project Scientist in the Physics Department at UC Berkeley.
During my astronomy career, I worked with large data sets from the Hubble Space Telescope, the Dark Energy Survey, and the Nearby Supernova Factory, employing optimization and sampling techniques to model data. I also wrote a bunch of open-source astronomy and statistics software in Python, Julia and C, much of which I continue to maintain. As part of BIDS, I investigated ways to make it easier for scientists to use programming tools to accomplish their research.
There's a bit more detail on my astronomy research here.
I'm an author of about 30 peer-reviewed journal articles in astronomy and physics. Here are a few highlights:
