Undergraduate Courses

KNPE 227 – Exercise Physiology

Research Summary

The goal of my research program is to advance our understanding of the integrative physiological mechanisms governing cerebral blood flow and cardiovascular function, with a focus on the effects of exercise and inactivity across the lifespan. My laboratory is currently focusing on 3 lines of investigation:

1) Cerebrovascular control during exercise

2) Cardiovascular consequences of spaceflight/bed rest/inactivity & countermeasures to protect cardiovascular health

3) Integrative cardiovascular responses to exercise

Graduate Student Opportunities

My laboratory is currently considering applications for MSc and PhD student positions. Prospective students are strongly encouraged to apply for scholarships and awards offered through the National Sciences and Engineering Research Council of Canada (NSERC), the Canadian Institutes of Health Research (CIHR), or Ontario Graduate Scholarship (OGS). Deadlines for these competitions generally fall in October — several months before the deadlines for our graduate programs. Only students who have already applied for funding from these external agencies will be eligible for the various internal scholarships and awards offered by Queen’s University to incoming students.

Bio:

Dr. Sarah Blacker is an Adjunct Assistant Professor in the School of Kinesiology and Health Studies at Queen’s University.  She received her PhD from the University of Alberta in 2015 and held Postdoctoral Fellowships at the Max Planck Institute for the History of Science in Berlin and at the Technical University of Munich, Germany, before returning to Canada to take up a SSHRC Postdoctoral Fellowship in the Department of Anthropology at York University in 2020.  She was a Lecturer in the M.A. Program in Science and Technology Studies at the Technical University of Munich from 2018-2020.  She has taught in the Health and Society Program at York University since 2021.
 
Dr. Blacker’s research and teaching are centered around racial health inequities, environmental health, and data justice.  Her research addresses racial health inequities through two current projects: 1) research on environmental health inequities and community-led environmental monitoring projects practicing data sovereignty in contexts of environmental contamination and climate change; and 2) research on the collection and uses of race-based health data with a focus on the uses of this data in the development of medical AI tools.  This research examines initiatives underway to create algorithmic fairness at the level of technology development, while also examining how health care practitioners address and mitigate the forms of bias and discrimination endemic to medical AI tools that are already in use.  Dr. Blacker’s recent research in these areas has been published in: The Lancet Digital Health; Social Studies of Science; The American Journal of Bioethics; Catalyst: Feminism, Theory, Technoscience; and the Journal of the Royal Anthropological Institute.

Dr. Wilson is a SSHRC-funded postdoctoral guest in the School of Kinesiology and Health Studies, working with the Sport Psychology PLAYS Research Group. He holds a Ph.D. in Human Kinetics from the University of Ottawa, an M.Sc. in Kinesiology from York University, and a B.Sc. Hon. in Kinesiology from McMaster University. Overall, his research examines how a better understanding of the psychology of learning can enhance participants’ developmental experiences in sport. Specifically, he explores how personal, social, and contextual factors can make learning (a) more effective, including learning skills, coaching approaches, and interest development; and (b) more sustainable, including resting experiences, team dynamics, and parenting.
