About Me

I am currently working at the intersection of population health and healthcare strategy, leveraging medical data (claims and EHR) to improve patient outcomes and reduce costs at Boston Medical Center. Previously, I spent time building and managing a team of data scientists at McKinsey & Company, focusing on workforce and organizational analytics for clients across a variety of industries.

I received my Ph.D in 2015 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, 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.
