My recent research focuses on experimental designs for computer experiments. I am particularly interested in sequential strategies for selecting points at which to run a computer simulator in order to optimize some performance measure related to the objectives of the computer experiment. This includes designs to identify the inputs that optimize the output, designs that identify inputs that improve the overall fit of a predictive model, and designs that identify inputs that yield a specified value or quantile for the output. My research has also involved problems in optimal experimental design, including optimal designs for regression, optimal block designs, and optimal designs for comparing treatments with a control. 

William Notz jointed the statistics faculty in 1984. He is a co-author of a popular book on the design and analysis of computer experiments, a co-author of the introductory statistics book, Statistics Concepts and Controversies, and a co-author of the introductory statistics book, The Basic Practice of Statistics. He is a Fellow of the American Statistical Association. He has served as the editor of the journal Technometrics and as editor of the Journal of Statistics Education.  He has served as the Chair of the American Statistical Association's Section on Physical and Engineering Sciences and as Chair of  the Section on Statistical Education. He has served as the Director of the Statistical Consulting Service, as acting chair of the Department of Statistics, and as an Associate Dean in the College of Mathematical and Physical Sciences at the Ohio State University.
