I am the statistician in the Data Analytics Program. I love the uncertainty that makes statistical inference interesting and the elegance of mathematical modeling. At Denison, I teach across the Data Analytics curriculum and mentor students on research projects. I enjoy working with undergraduates on both theoretical questions (yes, math!) and applied projects (yes, coding!). When I’m not working with data, I enjoy spending time with my kiddos: a busy toddler, a cat who runs the house, and a dog who happily goes along with it.

Research
My research is in sequential analysis, which studies how to make statistical decisions while data are still being collected in real time, rather than waiting until the very end. I am interested in questions such as when we have enough information to make a reliable decision, how to detect meaningful changes as they are happening, and how to design data collection more efficiently. I also collaborate with researchers in areas such as linguistics and health care, using statistical modeling and data analysis to answer real-world questions.
