Research interests: Bayesian inference, High-dimensional modeling, Causal inference, Environmental statistics
Before joining UF, I completed my PhD and postdoctoral training in the department of Biostatistics at Harvard University working with Francesca Dominici and Brent Coull. My research has mainly focused on developing statistical methodology to address problems in environmental health and comparative effectiveness research. I am passionate about many areas of statistics, but so far my methodological work has centered on high-dimensional modeling, causal inference, flexible Bayesian methods, and spatial statistics with applications to the environment.
Leo Duan is a Bayesian statistician interested in robust modeling, motivated by the applications of complex and big data. He obtained his PhD from University of Cincinnati in mathematics in 2015 and did his post-doctoral research in statistics at Duke University until 2018.

John Seppala is a new lecturer in the Department of Statistics, teaching undergraduate courses in statistics and actuarial science. He also advises students pursuing the Minor in Actuarial Science and the Florida Actuarial Student Society (FASS), the student actuarial club.
John’s most recent position was at Valdosta State University in Georgia, where he spent 16 years as a lecturer, teaching statistics, calculus, trigonometry, and algebra. Last year he passed the first four examinations given by the Society of Actuaries. John also has prior experience as a high school mathematics teacher in metro Atlanta and as an engineer with GE.
John received his Master of Statistics from UF in 2002 and is very excited to be returning to Gainesville with his wife Dana and their three boys, aged 15, 12, and 4.
Stephanie Stine is a Statistics Lecturer at the University of Florida. She earned her Master’s degree in Statistics from Texas A&M University. Prior to working at the University of Florida Stephanie was a high school teacher for twelve years. She completed her Bachelor’s degree in Computing and Mathematical Sciences in the United Kingdom which is where she originates from, having moved to the United States in 2007. In her spare time Stephanie enjoys spending time with her pets, computer gaming, watching the L.A. Dodgers baseball team and hopes one day to see a game at Dodger Stadium.
