University Professor of Computational Statistics
My interests include statistical computing, computational statistics, simulation, robust statistics, survey sampling, and computational finance. My interests in survey sampling include optimal design, calibration, and imputation. My interests in financial applications center primarily on the pricing of derivatives.
I am active in the American Statistical Association, especially the Statistical Computing Section and the Statistical Graphics Section. I am the Past Chair of the Graphics Section, and have held all of the offices of the Statistical Computing Section over the past quarter century. I am also on the council of the International Association for Statistical Computing.
