I'm a software engineer and open source community member. Most of my coding activities center around the Python data science stack. In particular, I'm a core maintainer of Dask and I work at Coiled where I focus on scaling Python. Previously I studied at the University of Wisconsin-Madison where I received my PhD in Physics.
