I was born in Lincoln, Nebraska, and attended Lincoln East High School, where I played cello, studied German, and participated in debate. For college I attended Harvard. I played cello in the Harvard-Radcliffe Orchestra and studied math, Russian, a bit of statistics, and a liberal arts mix of topics.  I remained at Harvard for graduate school in statistics during which time I worked summers at the U.S. Census Bureau. My doctoral dissertation topic was on statistical mixture models and their estimation with application to record linkage problems at Census and a Harvard psychology study on infants (clustering based on responses to novel stimuli). While at The University of Chicago as a senior lecturer, I met my wife Alice. We moved to Iowa and Maryland before coming to Vermont in 2017. We have three children, Lily, Chelsea, and Max, and live in Essex. My wife and I had brief experiences in Vermont before we knew each other, but our first encounter with the state together was through a small statistics workshop on total survey error in Stowe. Subsequently my daughters have attended Farm & Wilderness camps in Plymouth for several summers. I moved to SMC in 2017. We initiated the Statistics and Data Science degrees in 2018.
