Public Health Agency of Canada

Infectious Disease Prevention and Control Branch @130 Colonnade Road, Ottawa, ON

Current research and/or projects

Dr. Yan applies biostatistics, applied probability and mathematical models in the area of epidemiology of communicable disease transmission and control; also conducts research in the development of mathematical and statistical models and methods for investigating infectious diseases. He both manages a research group in disease modelling and publishes his own research in collaboration with other scientists.
