Biography

Saman joined the Department of Statistics as an Assistant Professor on July 1, 2010. He obtained a B.Sc. Honours special degree in Statistics from University of Sri Jayewardenepura, Colombo, Sri Lanka. In spring 2007, he completed a Master of Science degree in statistics under the supervision of Dr. Tim Swartz at Simon Fraser University. His thesis developed a Bayesian Analysis template for the Pacific Ocean Shelf Tracking project. This work was published in the Canadian Journal of Statistics as a discussed paper. He then continued to work with Dr. Tim Swartz for his doctoral thesis and completed his Ph.D. on June 2010. His thesis developed new theoretical and computational methodologies which deal with latent variable models and complex model structures for problems in sports, ordinal survey and network data. This work has been published in the Canadian Journal of Statistics and Australian & New Zealand Journal of Statistics.
