Research and Practice Interests
My research area is in Bayesian statistics, computational methods of large spatial and computer simulation data sets ("big data"), and uncertainty quantification. My primary applications have been in spatial and spatio-temporal statistics, sequential design, computer model calibration and image analysis.
