Dr. Shane Sweet, Director 

The overarching goal of Dr. Shane Sweet’s program of research is to enhance the lives of adults, whether healthy or living with chronic conditions/disease (e.g., adults with cardiovascular disease, spinal cord injury), by understanding and promoting physical activity and well-being and engaging community members. His program of research is therefore guided by three pillars: 

  1. Understand:  The purpose of this pillar is to understand physical activity participation and well-being by applying, testing and integrating theory, developing conceptual models and tracking changes over time. Research within this pillar is categorized by two streams: physical activity and well-being.  
  2. Promote: In this pillar, Dr. Sweet looks to increase physical activity and related constructs and enhance well-being through the two streams: persuasive messaging and intensive interventions. 
  3. Engage: The objective of this pillar is to incorporate the community in research, co-construct research with community, inform key end-users of the results and evaluate knowledge translation initiatives. As a result, consumer engagement and knowledge translation research are the two streams imbedded within this pillar

Dr. Lindsay Duncan, Director 

Dr. Duncan’s research is focused on investigating strategies to support the initiation and maintenance of physical activity and health behaviour change; particularly among those who face disproportionate risks from unhealthy behaviours (e.g., cancer survivors), or those who face disproportionate challenges to engaging in health behaviour (e.g., medically-underserved populations or the elderly). Dr. Duncan’s research focuses primarily on the promotion of exercise and physical activity; however, she has a keen interest in a wide variety of health behaviours including but not limited to:

  • Healthy eating
  • Smoking cessation
  • Prevention of alcohol, tobacco, and drug use.

Currently, Dr. Duncan is working on developing interventions to motivate and support physical activity participation women who are undergoing treatment for cancer. She also is collaborating on a series of projects in the evolving area of “serious games” (i.e., videogames intended for use in education or health) with the goal of developing innovative evidence-based educational materials and targeted videogame interventions for risk reduction and prevention in youth and young adults. Dr. Duncan believes strongly in taking a theory-based approach to health-behaviour research as well as partnering with community-based organizations to develop practically-relevant and sustainable interventions. Dr. Duncan maintains a network of multi-disciplinary research partners and is excited to expand her collaborative network.

Bradley Crocker, Master's Student 

Research Interests: Psychosocial determinants and discursive constructions of health and health-related behaviours, particularly in collegiate athletes and adolescents.

About me: As a varsity swimmer of five years, I’ve experienced first hand the demanding lifestyle student-athletes manage of balancing complex social, athletic, and academic roles. I’ve also witnessed how this lifestyle can shape student-athletes’ perceptions of what constitutes acceptable health-related behaviours, and some of the outcomes these behaviours lead to regarding mental and physical health. I was drawn to the TIE lab to partake in qualitative research as a means to better understand how student-athletes conceptualize health, and to potentially help inform interventions or the creation of new resources leading to the improved well-being of this population and others. 

Laura Hallward, M.A. '18, PhD Student 

Research Interests: Promoting physical activity among cancer survivors, particularly breast cancer and prostate cancer; preventing doping (or the use of performance-enhancing substances) among adolescent athletes 

About me: I have always led an active lifestyle either playing sports or engaging in different forms of exercise. With my interest in health and fitness, I joined the TIE lab during my undergraduate degree to help promote a healthy and active lifestyle among different populations. I also enjoying spending time exploring Montreal, from going for a run on the mountain to trying out new restaurants around the city.

Shannon Herrick, M.A. '18, PhD Student 

Research Interests: The intersection of sexual orientation, gender identity, and physical activity participation. More specifically, looking at how unique minority experiences within the LBGTQ+ community affect physical activity engagement.

About me: As an athlete, physical activity has always played a significant role in my life. As a member of the LGBTQ+ community, physical activity settings and practices have not always been the most inclusive. This inspired me to found Queerobics Montreal, a community organization and non-profit focused on creating safer spaces for physical activity engagement, and workshops for body positivity. Queerobics operates as my passion project, as well as ongoing inspiration for my master’s research.

Natasha Kaushik, Master's Student  

Research Interests: The impact of physical well-being, exercise and fitness on different populations and the role of culture and training in promoting physical exercise. Interventions via psychological motivation, mentoring and specific coaching. Of special interest to me is the use of exercise psychology to rehabilitate differently abled individuals and how cross cultural insights can enable a more holistic understanding, across all domains.

About me: Exercise and fitness have been an integral part of my life and I have worked in the fitness industry at a managerial and coaching capacity. I hold a Master’s degree in Clinical Psychology from Christ University, India and am licensed Zumba Fitness instructor with teaching experience of over three years. Outside of Zumba, I love hiking, CrossFit and Spin. In my free time, I like to cook, spend time with animals, travel and pick up new languages.

Emilie Michalovic, PhD Candidate 

Research Interests: Physical activity and exercise in special population, especially those living with chronic obstructive pulmonary disease (COPD); exercise promotion for inactive adults.

About me: Exercise psychology has been a field that I have been interested in for several years, beginning in my second year of my undergraduate degree in Kinesiology. I have always been an active athlete, participating in many sports; but as a university student, I found myself becoming more and more interested in exercise and health psychology. Since then, I have becoming interested in studying individuals living with chronic obstructive pulmonary disease (COPD), investigating ways that physical activity is limited in their lives and how it affects their quality of life and well-being.

Zhiyang (George) Shi, M.A. '19, PhD Student 

Research Interests: Using a peer-led self management program for increasing the participation of physical activity and quality of life among adults with physical impairments.

About me: I completed my undergraduate major in Sports Rehabilitation at Tianjin Medical University (China). Throughout my undergraduate degree, I became strongly interested in encouraging people living with mobility impairments to partake in physical activities and exercise. I am very enthusiastic about promoting people’s health and their quality of life. In my spare time, I enjoy playing basketball and swimming. These activities make me energetic and confident every day.

Tayah Liska, Master's Student

Research Interest: How engagement, and adherence to, physical activity effects the quality of life amongst people living with chronic diseases or injuries.

About Me: As an athletic individual and sports enthusiast, I’ve have always had great interest in physical activity, exercise, sport, and health promotion. This interest led me to studying kinesiology, completing a Bachelor of Science in Human Kinetics with Honours this past year at St. Francis Xavier University. As much as I am passionate about exercise and sports, I have developed a great interest in research. Having learned about the TIE Lab’s focus on physical activity interventions, adaptive physical activity, and health behaviour theory, I felt as though this research environment would allow me to growth my interest further. As a first year master’s student in the TIE Lab, I am very excited to further explore my research interest, gain insight to new areas of research, and learn more about physical activity interventions!

Olivia Pastore, PhD Student

Research Interests: Understanding the psychological processes and self-care strategies among peer mentors with spinal cord injury (SCI); using a self-compassion intervention to reduce compassion fatigue and enhance well-being among peer mentors with SCI; exercise promotion for insufficiently active adults

About me: As an athlete and avid exerciser, I have always been interested in understanding the psychological processes behind engaging in, and maintaining physical activity behaviour. Being in the field of exercise psychology, I have been able to fulfill my passion for helping individuals to become more active through my research. Alongside this research interest, I have also always been so passionate about helping others increase their well-being and quality of life, specifically through being self-compassionate. I strongly believe that self-compassion is an important psychological resource that can be useful to anyone. What excites me the most about my research is the practical component and the opportunity to work with these individuals first-hand in a community setting. To me, there is nothing more rewarding than seeing your research make a positive impact. It is a huge honour for me to be able to work in the TIE lab with such an amazing team and I'm so excited for what we will all accomplish!

Pierre Lepage, Research Assitant

Research Interests: Adapted physical activity and the impact of peer-mentorship in physical activity interventions.

About me: I completed my M.A. in Sport Psychology at McGill University during which I looked at the learning experiences of youth parasport coaches. Following the submission of my thesis, I had the opportunity to work in the TIE lab as a research assistant and thus transitioning from parasport to adapted physical activity. After working around parasport coaches and athletes, I am now involved in various projects that are designed to help people with physical disability being more physically active. Outside of research, I am playing and coaching soccer, trying to share my passion for a sport that had a tremendous impact on my life.
