Assistant Professor

School of Information Sciences, University of Illinois

Sep 2016 – Present Illinois

Research Scientist

NCSA, University of Illinois

Jun 2014 – Aug 2016 Illinois
At the National Center for Supercomputing Applications, I built a research group to conceptualize, develop and understand tools for data exploration and visualization. In collaboration with others at the NCSA, I worked to advance the National Data Service and other initiatives.

Associate Research Scientist

Columbia University Astronomy

Jan 2014 – May 2014 New York City
Supported by the NSF SI2-SSE grant ACI-1339624 (proposal available here) I was an associate research scientist at Columbia.

NSF CI TraCS Postdoctoral Fellow

Columbia University Astronomy

Jan 2011 – Dec 2013 New York City
As part of the NSF CI TraCS fellowship program, I spent three years at the Columbia University Astronomy Department developing computational tools for astrophysical simulations in collaboration with Prof Greg Bryan.

Postdoctoral Scholar

University of California San Diego

Jul 2009 – Dec 2010 San Diego, CA
I worked as a postdoc with Prof Mike Norman at the Center for Astrophysics and Space Sciences at UCSD.

A Little Bit of Endianness

(Confession time: I did not even realize I was mildly-punning in that title.) Over the last few months, my hobby-time has mostly been focused on some reverse engineering of old DOS games I played as a kid.

yt: Internal and External Ecosystems

I think I’ve talked myself into proposing a big change in yt. I’m not the “boss” of yt, so it might not happen, but I’ve kind of worked up my courage to make a serious suggestion.

Loading data in yt: Can we make it better?

In this blogpost, I walk through the annoying bits about loading unknown data into yt.

Kaitai Struct and Scientific Data

tl;dr: kaitai struct is awesome. File formats can be pretty annoying – especially when you figure them out through weird combinations of reverse-engineering, hand-me-down code and trial-and-error. What we’ve ended up with in yt is a bunch of data formats where the process of conducting the IO is all mixed up with the description of that IO.



yt is an open-source python package for analyzing and visualizing volumetric data.

Crops in Silico

Crops in Silico is an integrative and multi-scale modeling platform to combine modeling efforts toward the generation of virtual crops, open and accessible to the global community.

Whole Tale

Whole Tale is an initiative to build a scalable, open source, web-based, multi-user platform for reproducible research.
