Kate DupuisKate Dupuis, PhD, CPsych

Schlegel Innovation Leader

Kate Dupuis joined the Centre as the Schlegel Innovation Leader in Arts and Aging in 2017. Kate is a registered Clinical Neuropsychologist and a researcher whose work lies at the intersection of arts, health, and aging. In her research, Kate seeks to identify both the potential personal and systemic barriers to participation in the arts, how we can facilitate arts engagement in older adults, and what the terms being creative or artistic mean to us at different stages of our lives. Kate strives to understand how the arts can benefit all domains of health and well-being, including cognitive, physical, emotional and social well-being, and how we can encourage and foster creativity and innovation across the lifespan. At Sheridan College, Kate is also a professor in the Faculty of Applied Health and Community Studies.

Karen SlonimKaren Slonim, PhD, MA, MPH, BA, BEd

Karen Slonim joined the Centre for Elder Research team in September 2022. She is a medical anthropologist, health educator, scholar and teacher who has tremendous respect for the knowledge and wisdom held by our older adults. To this end, she strives to base her research in collaborative knowledge generation through co-creation with seniors.  For the past 12 years she has worked in primary care as a provider and applied researcher amplifying the voices of care partners; exploring frailty, cognitive impairment, and end-of-life care; advocating for engaged advance care planning; and designing health promotion activities that reflect the needs, interests, and values of our elders. Equity and inclusion are also of paramount importance to Karen, so her work is often rooted in social determinants of health and cross-cultural understandings.

A lifelong learner, Karen holds a PhD in anthropology from the University of Missouri-Columbia where she was a Life Sciences Fellow. She has also completed a master of arts in the anthropology of health (McMaster University), masters of public health (University of Waterloo), bachelor of arts in anthropology (McMaster University) and a bachelor of education in adult education (Brock University). She is a certified smoking cessation counsellor, Craving Change instructor, chronic disease self-management and chronic pain self-management facilitator, Living Life to the Full facilitator, Powerful Tools for Caregivers trained, and regional champion under HPCO's Health Care Consent and Advance Care Planning Community of Practice.

Kathleen BéginKathleen Bégin

Kathleen has an MBA from Athabasca University and is a Certified Financial Planner. She earned the Elder Planning Counsellor (EPC) designation in 2011. She is a professor and program coordinator for the finance diploma programs at Sheridan College. Her experience in financial planning has taught her the importance of understanding elder issues and how older clients are served. This has influenced the way she teaches, in courses such as Retirement and Estate Planning, where she now incorporates more content about the concerns of elders, rather than just focusing on the number crunching. Current and changing demographics demand that our graduates have access to the knowledge and skills they need to work with older adults and their families.
