As a statistician, I have had the pleasure of delving into a broad spectrum of scientific problems, from evolutionary biology to engineering to drug development. Thinking about such a variety of problems is the chief attraction of statistical science for me. To share that enthusiasm with graduate and undergraduate students is a pleasure.

In the department, I spend much of my time directing dissertation research. I also enjoy working on research with my former students, many of whom have become like an extended family.

I am a member of the American Statistical Association, the American Association for the Advancement of Science, and the Union of Concerned Scientists. Personally, I enjoy reading, especially history and science, hiking, and scale model building.
