About Me

I am currently a PostDoc at Stanford working with Christopher Re. In August of 2019, I graduated with a PhD from Paul G Allen School for Computer Science and Engineering at the University of Washington in Seattle. I was part of the Database Group and advised by Dan Suciu and Magdalena Balazinska.

For my undergraduate degree, I went to Carleton College in Northfield, MN, where the city's motto is "Cows, Colleges, and Contentment" and graduated in 2013 as a Computer Science and Mathematics double major.

Research and Work Experience

My research interests are primarily focused on building an Open World Database System that inherently treats relations as biased samples of some unknown population and by some population aggregate information, automatically corrects of sample selection bias. I am also interested in how to generate a query-able summary of data that can the be used for running ad-hoc, exploratory, and approximate queries. My other broad research interests include Machine Learning and Data Visualization

I am one of the 2015 winners of the NSF GRFP in Computer Science. In the summer of 2016 and 2017, I interned at Microsoft Research as a PhD research intern, and in the summer of 2015, I interned at Tableau as a software developer. From the summer of 2012 to the spring of 2015, I interned at Sandia National Laboratories working on high performance computing and image reconstruction.
