Colin Faulkner

Activist, biologist, and literary enthusiast – Colin is deeply interested in seeking health equity for older adults. His work at Women’s College Research Institute (WCRI), which investigates individual-level factors associated with health care use, highlights gender-specific changes that we should consider to improve the health of older women and men. Colin is motivated by the idea that his research has a direct impact on patients and all Ontarians.

In his spare time, Colin enjoys reading Victorian literature and he challenges himself to try cooking with a new recipe every weeknight.

Dr. Katrina Piggott

Dr. Katrina Piggott is a General Internist and Geriatrician. She is a Clinical Associate at the University Health Network, based at Mt. Sinai Hospital and she is currently completing her MSc in Quality Improvement and Patient Safety at the Institute of Health Policy, Management and Evaluation.

Her work on WCRI’s aging research team aims to improve the care for older adults across a continuum of healthcare settings, with a particular interest in de-prescribing, antibiotic stewardship, and reducing harm associated with medications.  

In her spare time Katrina enjoys cycling, climbing and hiking with her family.

Stephanie Read, PhD

Stephanie Read, PhD is a postdoctoral fellow at Women’s College Research Institute, with expertise in quantitative research methods in large administrative datasets. She received her MSc in Public Health Research and her PhD in epidemiology and biostatistics from the Usher Institute at the University of Edinburgh in Scotland. 

Stephanie’s main research interests are in the prevention of diabetes and its complications. In her previous post-doctoral role at the University of Edinburgh, Stephanie led collaborative research that aimed to reduce the burden of cardiovascular disease in people with Type 2 diabetes. Her research involved the development of decision-support tools to help clinicians identify people who would benefit from cardiovascular disease risk-reducing therapies.  

At WCRI, Stephanie is utilizing her expertise to develop decision-support tools to identify postpartum women at high-risk of developing Type 2 diabetes who would benefit from risk-reducing interventions. In addition, Stephanie is leading research examining prescribing cascades in vulnerable older adults. 

In her spare time, Stephanie is an avid hiker and regularly plays soccer (or football as she would call it!)

Rachel Savage, PhD

Rachel Savage, PhD is a postdoctoral fellow at Women’s College Research Institute, with expertise in both quantitative and qualitative research methods.  She received her PhD in epidemiology from the Dalla Lana School of Public Health at the University of Toronto and a MSc in epidemiology from the world-renowned London School of Hygiene and Tropical Medicine in London, UK.  

Rachel has over 10 years of local and provincial public health experience and conducts applied, collaborative public health research that aims to improve the health of vulnerable populations, including older adults, immigrants and women.  Her research is supported by a Canadian Institutes of Health Research (CIHR) postdoctoral fellowship.

At WCRI, Rachel is leading a CIHR-funded program of research designed to measure the burden of loneliness and social isolation in older adults and their impact on the health system.  This work also brings together diverse stakeholders to propose community-based solutions.  In addition, Rachel is currently examining older adults’ expectations and priorities for aging, and their risk for experiencing certain prescribing cascades.  

In her spare time, Rachel has her hands full with her son and newborn daughter.
