About Me

I am currently a Senior Data Scientist with Organizational Solutions at McKinsey & Company. In August 2015 I received my Ph.D from the Quantitative Psychology program at the University of Virginia, where I worked with Brian Nosek, Sara Rimm-Kaufman, and Timo von Oertzen on projects focusing on quantitative challenges found in applied educational research. I also participated in the July 2015 Insight Health Data Science program in Boston. My interests include statistics, data mining/machine learning, education, and open science. If you look around, you will find some blog posts, publications, and relevant code. You can also see a copy of my resume here.
