Cascadia 2023

Annual Cascadia Symposium on Environmental, Occupational, and Population Health


January 5-6, 2023 (Thursday 11am - Friday 12pm)

Semiahmoo Resort, Blaine, WA


Cascadia 2023 is sponsored by the Northwest Center for Occupational Health and Safety (NWCOHS), the University of Washington Department of Environmental and Occupational Health Sciences (DEOHS), and the Pacific Northwest Agricultural Safety and Health Center (PNASH).



This is a joint meeting of the University of Washington (School of Public Health - Dept of Environmental and Occupational Health Sciences & Dept of Health Systems and Population Health); University of British Columbia (School of Population and Public Health); Simon Fraser University (Faculty of Health Sciences); and Oregon State University (College of Public Health and Human Sciences).

This intimate conference provides faculty, staff, and students a forum to share new ideas and current or evolving research through plenary sessions, short (20-minute) podium presentations, ignite presentation (5 min) and posters, small group discussions, and socializing. This meeting is a great opportunity for cross border conversations and collaborations.

This year’s conference will feature four thematic areas. However, we welcome abstracts on any topics broadly related to environmental, occupational, and population health.




Bates Memorial Lecturer

Dr. Tim Takaro

Bio: Dr. Tim Takaro is a physician-scientist trained in occupational and environmental medicine, public health and toxicology. Dr. Takaro’s research focuses on the links between human exposures and disease, and determining effective public health based preventive solutions to such risks.  His body of work includes markers for medical surveillance, exposure assessment, and disease susceptibility with a focus on immunologic lung disease, human health and war, clinical occupational and environmental health and population resiliency in the health effects of climate change. His climate change work focuses on water, extreme weather events and gastro-intestinal illness and the role of aero-allergens in the development of asthma and allergy in children. He initiated the exposure assessment component of the Canadian Healthy Infant Longitudinal Development (CHILD) study, served as the Canadian co-chair of the Health Professionals Advisory Board to the International Joint Commission on border waters and was a lead author for Health of Canadians in a Changing Climate: Advancing Our Knowledge for Action (Feb 2022). A lack of government response to the overwhelming evidence that we must stop building new large fossil energy infrastructure has led him into non-violent civil disobedience to stop the Trans Mountain pipeline expansion and other such projects. In 2022 Dr. Takaro became a professor emeritus of Simon Fraser University where he continues to mentor and do research with knowledge mobilization.
