My appointment at George Mason is in the School of Computational Sciences, in which there is an active program in computational statistics. I am also affiliated with the Department of Applied and Engineering Statistics and the Center for Computational Statistics. (What is computational statistics? Here's some background.)
I have been at George Mason University since 1992. Before that I was with IMSL in Houston (beginning in 1979), where as director of research and design, I was in charge of design of the Fortran and C numerical libraries and other scientific software. Before that I was associate professor of statistics at Iowa State University. Before that I led a life of leisure as a student. A biographical sketch is available in the usual CV style.
My research interests include statistical computing, computational statistics, simulation, and robust statistics. I have also recently become interested in topics in survey sampling, including optimal design, calibration, and imputation.
I've been working on some books lately. A book that provides an introduction to computationally-intensive methods in statistics is Elements of Computational Statistics (here's Amazon's site ). Two books that cover topics in statistical computing (numerical analysis for statistical applications) are Random Number Generation and Monte Carlo Methods Second Edition (here's Amazon's site) and Numerical Linear Algebra for Applications in Statistics (here's Amazon's site ). Another book on statistical computing that I'm working on is Optimization Methods for Applications in Statistics .
I am active in the American Statistical Association and currently serve as Chair of the Statistical Graphics Section of the ASA. I am also on the council of the International Association for Statistical Computing.
I have some information on courses I am teaching or have recently taught at George Mason.
I am proud of my current and past PhD students
