Research Group in Biostatistics (RGB)

I belong to the Research Group in Biostatistics (RGB), a group of statisticians and biostatisticians in the Department of Mathematics and Statistics who carry out methodological research in statistics with emphasis on its applications in medicine and health, biology, genetics, the environment, and other related fields.

I am also a member of the University of Calgary Biostatistics Centre (UCBC), a multi-faculty initiative “housed” in the O’Brien Institute for Public Health in the Cumming School of Medicine.  The UCBC administers the interdisciplinary specializations in Biostatistics of the MSc-thesis and PhD joint programs of the Departments of Community Health Sciences and Mathematics and Statistics.
