Research in Sweeney Lab:

Our research focus is on cardiometabolic diseases. Thus, understanding mechanisms underlying diabetes or heart failure is a major interest. Research in our lab is funded by CIHR, NSERC, IDRC, Heart & Stroke Foundation and Thalassemia Foundation of Canada.

Our collaborative network includes research groups across Canada as well as in Hong Kong, Thailand, South Korea and United Kingdom. Our work may aid the development of therapeutic strategies for the treatment of cardiometabolic diseases in obesity. Indeed, we have close partnership with a pharmaceutical company from USA to aid in the development of adiponectin-based therapeutics.


Information for Prospective Graduate Students

Our lab is open for both PhD. and MSc. students. We look for potential graduate students who have related research experience and demonstrated skills, a strong academic record, are creative and highly motivated, and whose interests match on-going work in the lab. Prospective students may provide a statement of your interests, a CV and (unofficial) transcript. Letters of recommendation will be requested prior to acceptance for graduate school.
