Josh Lawson is an Associate Professor in the Department of Medicine at the University of Saskatchewan in Saskatoon, Canada. His research is based out of the Canadian Centre for Health and Safety in Agriculture (CCHSA), also in the College of Medicine at the University of Saskatchewan. His training is from Simon Fraser University in Vancouver (BSc), the University of Saskatchewan in Saskatoon (MSc), and the University of Alberta in Edmonton (PhD). Throughout his training he has focussed on epidemiology and biostatistics. His primary areas of interest are pediatric asthma and respiratory epidemiology but he is also interested in various aspects of child health, lung health, and rural health. The majority of his research program is focussed on the urban-rural gradient and the reasons for geographic variation in childhood asthma. He currently holds a Canadian Institutes of Health Research and Lung Association of Saskatchewan partnered Investigator Award in Paediatric Asthma. He has been involved in several population based studies as well as studies using large administrative and research based databases.
