Computational statistics, with applications to fire science; statistical process control; statistical education. Most recently, I have been focusing on visualization methodology, using a class of techniques called Data Sharpening.
Courses & Teaching
Modelling and Simulation. Predictive Modelling. Data Visualization.
Since completing my PhD in Statistics at the University of Western Ontario, I have held positions at a number of universities, including Western for 14 years where I attained the rank of Full Professor and was Chair of the Statistics Graduate Program for 5 years. In 2014, I took the opportunity to become Head of Computer Science, Mathematics, Physics and Statistics at UBC’s Okanagan campus. The following year I became Deputy Director of the Canadian Statistical Sciences Institute (CANSSI).
My research in statistics has often been motivated by scientific problems, coming from psychology, biology, medicine, engineering and physics. My methodological research is concerned with smoothing and inference techniques as they apply to data visualization and process monitoring.
