Interview

I was born in Lincoln, Nebraska, and attended Lincoln East High School, where I played cello, studied German, and competed 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 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). I was promoted to Associate Professor at Iowa State University and Professor at George Washington University before joining Saint Michael’s College in 2017.
