About Me

I have taught a variety of courses that are theoretical (calculus- or analysis-based) and applied (non-mathematical) statistics. These include undergraduate level statistics courses for engineering majors, business majors, mathematics majors, and research workers in the natural sciences; and graduate level mathematical statistics and a topics course in mathematics (probability theory).
