About Me

I am a research statistician at Battelle. I received my PhD in Statistics from Ohio State, working with Prof. Yoonkyung Lee. I am interested in machine learning applications in statistics. My dissertation dealt with dimensionality reduction, matrix factorization, and classification with large binary and count datasets.

In the past, I worked as a graduate research associate for the Campus Transit Lab in the Department of Civil, Environmental and Geodetic Engineering with Prof. Prem Goel, Prof. Rabi Mishalani, and Prof. Mark McCord. We developed methods to estimate origin-destination patterns of travelers on public transportation. I was also a statistical consultant for IGS Energy. In the summer of 2014, I was a fellow in the Eric & Wendy Schmidt Data Science for Social Good Fellowship at the University of Chicago.

I was part of the team that won the 2013 Capital One Student Modeling Competition, which involved recommending new merchants to each customer. Find out more about me from a small profile I wrote for the OSU Statistics student blog, a story that the College of Arts and Sciences did on my summer fellowship, and an interview I had with Amstat News.
