As Canada’s population continues to age, understanding how to support healthy aging has never been more important. MSc student Taronish Kotwall is contributing vital research to this growing area through her work on executive function, depressive symptoms, and the power of social connection among middle aged and older adults.
Using data from over 30,000 participants in the Canadian Longitudinal Study on Aging (CLSA), Taronish’s thesis investigates how baseline executive function is associated with depressive symptoms over time—and how social connection (social isolation and functional social support) may modify this relationship. Her research will help build evidence around how strong social connections can promote healthy aging and cognitive resilience in Canadians.
Beyond her thesis, Taronish has been an active leader and contributor within the School of Public Health Sciences and the broader research community. She has served in multiple student executive roles, guest lectured in an undergraduate public health course, and gained valuable qualitative research experience through a CRE MSD funded project focused on personal support workers. She has also presented at several conferences, including the Symposium on Aging Research, Symposium on Neuroscience Research, and the Research and Practice in Health Sciences Conference.
We’re proud to celebrate Taronish’s impact, dedication, and leadership in advancing research on aging and mental health.
