I joined the Cornell faculty in 1978 as a member of the Biometrics Unit in the Department of Plant Breeding and Biometry; this became the Department of Biometrics, and subsequently the Department of Biological Statistics and Computational Biology. I am also a faculty member in the Department of Statistical Science. I was the Director of Undergraduate Studies for the Biometry and Statistics program from 1991 to 2009. I retired from active faculty status in December 2011.
My professional activities are centered on the application of statistical methodology to research questions from a wide range of areas in the biological, physical, and social sciences and business. This can involve the use of existing methods and techniques, the development of new methods better suited to the questions of interest, or a combination of the two. I am interested in statistical approaches and techniques for collecting the proper data, including experiment design and sampling design, and for analyzing data in order to draw appropriate conclusions through statistical inference.
