I was drawn to the discipline of statistics by a fascination with randomness, and by the way it blends mathematics and scientific content. I have enjoyed interactions with researchers in many areas, especially the natural sciences, which have given me opportunities to learn about these fields and to make contributions to them. Underlying these separate analyses are paradigms of statistical methodology that have been developed over the last 100 years. This evolution accelerates as statisticians confront new challenges in the information age.
I am especially interested in developing methods for analyzing data that arise in the form of random functions, such as time series, and which involve large quantities of data and computationally intensive analysis. Much of my recent work has centered around two projects in astronomy: detecting objects in the outer regions of the solar system (the Kuiper Belt) and detecting gamma-ray pulsars.
