Complete these steps before you reach out to a faculty member!
- Familiarize yourself with program requirements. You want to learn as much as possible from the information available to you before you reach out to a faculty member. Be sure to visit the graduate degree program listing and program-specific websites.
- Check whether the program requires you to seek commitment from a supervisor prior to submitting an application. For some programs this is an essential step while others match successful applicants with faculty members within the first year of study. This is either indicated in the program profile under "Admission Information & Requirements" - "Prepare Application" - "Supervision" or on the program website.
- Identify specific faculty members who are conducting research in your specific area of interest.
- Establish that your research interests align with the faculty member’s research interests.
- Read up on the faculty members in the program and the research being conducted in the department.
- Familiarize yourself with their work, read their recent publications and past theses/dissertations that they supervised. Be certain that their research is indeed what you are hoping to study.
- Compose an error-free and grammatically correct email addressed to your specifically targeted faculty member, and remember to use their correct titles.
- Do not send non-specific, mass emails to everyone in the department hoping for a match.
- Address the faculty members by name. Your contact should be genuine rather than generic.
- Include a brief outline of your academic background, why you are interested in working with the faculty member, and what experience you could bring to the department. The supervision enquiry form guides you with targeted questions. Ensure to craft compelling answers to these questions.
- Highlight your achievements and why you are a top student. Faculty members receive dozens of requests from prospective students and you may have less than 30 seconds to pique someone’s interest.
- Demonstrate that you are familiar with their research:
- Convey the specific ways you are a good fit for the program.
- Convey the specific ways the program/lab/faculty member is a good fit for the research you are interested in/already conducting.
- Be enthusiastic, but don’t overdo it.
G+PS regularly provides virtual sessions that focus on admission requirements and procedures and tips how to improve your application.

Background: Using wearables to self-monitor physical activity is a promising approach to support self-management among persons with arthritis. Little is known, however, about ethical issues (benefits and downsides) that may be experienced by persons with arthritis when using a wearable. Better understanding of these experiences is needed if wearable technology is to be incorporated in arthritis self-management in ways that are ethically aware.Objective: To develop understanding of the perspectives of persons with arthritis on their use of a physical activity wearable in their everyday self-management. Methods: The thesis consists of 3 projects, involving: 1) a meta-synthesis of qualitative evidence that included an exhaustive search of 5 electronic databases and a thematic synthesis of eligible articles; 2) a secondary analysis of qualitative interviews with 21 participants with knee osteoarthritis, following their use of a wearable as part of a physical activity counselling intervention study involving a physiotherapist (PT); 3) a social constructivist application of grounded theory to conduct and analyze qualitative interviews with 14 participants with rheumatoid arthritis, following their use of a wearable as part of a physical activity counselling intervention study involving a PT. Each project draws on a relational ethics lens to explore benefits and downsides identified in participants’ perspectives. Findings: Across projects, participants conveyed 1) how using a wearable expanded and/or challenged their capability of making autonomous choices to be more physically active or not; 2) how using a wearable enhanced and/or threatened to undermine mutual trustworthiness in their relationship with the PT; 3) how using a wearable helped or challenged them in preserving a valued sense of self, in which independence and productivity play a role. Using a relational ethics lens drew attention to how participants’ experiences intertwined with desires to maintain a positive moral identity shaped by the context in which they live. Conclusions: The thesis contributes empirical evidence of relational ethics issues to sparse literature on how persons with arthritis experience using a physical activity wearable positively and/or negatively. It brings to light salient ethical issues pertaining to relational autonomy experienced in participants’ relationships with themselves and health professionals when using a wearable.

Objectives: (1) Develop a protocol for a pilot randomized controlled trial (RCT) of a novel physical activity (PA) counseling intervention to increase bouted moderate-to-vigorous physical activity (MVPA) time (bout ≥ 10 minutes at ≥ 3 Metabolic Equivalents [METs]) and decrease bouted sedentary time (bout > 20 minutes at ≤ 1.5 METs) for people with knee osteoarthritis (OA), and (2) conduct a secondary baseline analysis to assess the relationships between a measure of patient engagement and bouted MVPA time, as well as bouted sedentary time. Methods: A protocol for a pilot RCT was developed and published. Feasibility objectives related to study processes, resources, management, and effectiveness were set. Inclusion criteria were a diagnosis of knee OA or having experienced four weeks of knee symptoms during the last year, no inflammatory arthritis, and no contra-indications to being active. Patient engagement was measured with the Partners in Health Scale (PIH). MVPA and sedentary time were measured with the BodyMedia SenseWear Mini (SW). Knee OA status was assessed with the Knee injury and OA Outcome Score. Bivariate and stepwise regression analyses were performed to estimate the relationship between PIH and bouted MVPA/sedentary time. Results: Participants (female = 28, male = 6), were aged [mean (standard deviation [SD])] 55.5 (8.6) years, with a BMI of 27.2 (4.7) kg/m². The sample indicated a PIH of 24.4 (16.4), 53.9 (62.4) minutes of daily bouted MVPA, and 508.9 (178.9) minutes of bouted sedentary time. Regression analysis [b (standard error [SE]) where b indicates estimated regression coefficient] found log-transformed bouted MVPA was not associated with PIH, but was negatively associated with age, b = -0.042 (0.018; p
INTRODUCTION: The home-based Otago Exercise Program (OEP) has been shown to reduce the occurrence of falls in community-dwelling seniors. A new OEP DVD was recently developed to be delivered to people living in rural communities with minimal coaching by a physical therapist (PT). This thesis aimed to: 1) understand older adults’ experiences in using the DVD-delivered OEP, and 2) explore barriers and facilitators to implementing the DVD-delivered OEP from the participants’ perspectives. METHODS: Thirty-two rural community-dwelling older adults (≥75 years old) who participated in a six-month DVD-delivered OEP study were invited to participate in this qualitative study. Two small group interviews were initially conducted to explore the breadth of participants’ experiences with the program. These were followed by semi-structured individual interviews to gain an in-depth understanding of these experiences. An inductive constant comparison analysis involving coding of transcripts was performed. To ensure methodological rigour, field notes, journaling and an audit trail were maintained and peer-review took place.RESULTS: Five participants partook in group interviews and 16 in individual interviews. Three themes emerged. Theme 1, ‘The OEP DVD: Useful training tool but in need of more pep’, reflected participants’ experiences that the DVD provided important guidance at program onset, but was too slow and low-energy for longer-term use. Theme 2, ‘Providing greater control over one’s exercise regimen, but sometimes life gets in the way of staying active’, described participants’ appreciation of the program’s flexibility, but personal health concerns and everyday lives imposed challenges for adhering to the program. Theme 3, ‘Social creatures: Wanting greater human connection during exercise’, described how some participants desired further social interactions for enhancing motivation and sense of guidance. CONCLUSION: PTs prescribing the OEP should inform participants of the option to use the manual whenever they feel they have taken full advantage of the DVD and to perform the program with friends and family. The importance of exercise even when living with health problems should be raised at program onset, and methods of integrating the program with everyday activities should be promoted.
Objective: To determine the association between cumulative occupational physical load (COPL) to the knee and the presence of symptomatic osteoarthritis (SOA) and magnetic resonance imaging–defined osteoarthritis (MRI-OA).Methods: Cross-sectional analyses of symptomatic and asymptomatic (n=327) individuals were performed. Inclusion criteria for the symptomatic participants were: 1) having pain, aching, or discomfort in or around the knee on most days of the month at any time in the past; 2) having any pain, aching, or discomfort in or around the knee in the past 12 months. Asymptomatic participants responded “no” to both knee pain questions. COPL was calculated using a self-reported level of activity (five levels) and participation in knee bending/kneeling tasks (three levels) for each occupation held. SOA was defined by the Kellgren Lawrence x-ray grade ≥2, plus the presence of knee pain, as defined by the study inclusion pain criteria. MRI-OA was defined using the criteria specified by Hunter and associates. Logistic regression analyses, adjusted with population weights, were used to examine the associations between COPL (reference group=the lowest COPL quarter) and the presence of SOA and MRI-OA, respectively, after controlling for age, female sex, body mass index, and two-way interactions.Results: Participants (women=167, men=160) were on average 58.5 (SD=11.0) years old with a BMI of 26.3 (SD=4.7). Of those, 102 (31.2%) participants had SOA. For SOA, a monotonic statistically significant relationship was found between COPL 4 (highest quarter; odds ratio (OR)=8.16; 95% CI=1.89, 35.27) and COPL 3 (OR=5.73; 95% CI=1.36, 24.12) versus COPL 1. For MRI-OA, monotonic and statistically significant associations were found in COPL 4 versus 1 (OR=9.54; 95% CI=2.65, 34.27); COPL 3 versus 1 (OR=9.04; 95% CI=2.65, 30.88); COPL 2 versus 1 (OR=7.18; 95% CI=2.17, 23.70). Conclusion: COPL is a significant risk factor for knee OA. Dose response relationships between COPL and both SOA and MRI-OA were found. This study provides new insight into the role of occupation in knee OA, although the results should be interpreted cautiously due to limitations associated with the cross-sectional study design.
Background:Providing rehabilitation services to meet the needs of rural residents and address poor health outcomes requires overcoming the challenges of geography, limited referral options and a shortage of occupational therapists (OTs) and physical therapists (PTs). However, little is known about how rehabilitation professionals in rural areas enact their practice to meet and overcome these challenges. To address this gap and contribute to enhancing health for rural residents, this research constructed an understanding of rural rehabilitation practice from the perspectives of OTs and PTs in rural British Columbia (BC). Methods: This qualitative study employed a purposive sample of OTs and PTs in rural communities (population
