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 "Requirements" 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: The high mortality and morbidity rates associated with diabetes are mainly attributed to its cardiovascular complications. It remains questionable whether diabetes has a general deleterious effect on the vasculature, or if different arteries exhibit differential vulnerability to the diabetic milieu. This thesis compared the functional adaptation of three arteries: the aorta, carotid and femoral arteries, to the diabetic milieu present in db/db mice, and elucidated the mechanisms underlying the arteries' differential adaptation. Additionally, the functional and molecular alterations in the aorta and femoral artery in response to moderate-intensity exercise training were compared. Methods: Vasodilatory and contractile responses were examined in isolated aortae, carotid and femoral arteries from db/db and control mice to assess the endothelium and vascular smooth muscles' functions. Additionally, the protein expressions of endothelial nitric oxide synthase (eNOS), Akt, cyclooxygenase and superoxide dismutase (SOD) isoforms were examined. In parallel, plasma markers of glycemia, oxidative stress, inflammation, and dyslipidemia were measured. Thereafter, a correlation analysis was performed to estimate the strength of association between plasma variables and vascular responses. Results: The aortae of db/db mice exhibited a progressive impairment in endothelial and vascular smooth muscle functions. The carotid artery was the most resilient and maintained unaltered functional responses in db/db mice, likely because the carotid artery, in contrast to the aorta, relaxes in response to superoxide anion or peroxynitrite. The femoral arteries of db/db mice showed reduced endothelium-dependent hyperpolarizing factor-mediated vasodilatation and attenuated contractile responses, probably due to the lack of expression of extracellular SOD in the femoral artery. The benefits of exercise training were confined to nitric oxide-mediated vasodilatation in the aortae and femoral arteries of db/db mice, and were associated with increased eNOS/Akt and SOD expressions and reduced cardiovascular risk factors.Conclusions: Substantial heterogeneity exists between the aorta, carotid and femoral arteries both at functional (signalling pathways) and molecular levels (protein expression) under physiological and diabetic conditions. Understanding regional differences in vasomotor control, coupled with advanced drug delivery systems will open new venues for developing therapies that target specific vascular beds with minimal systemic side effects.
