Complete these steps before you reach out to a faculty member!

Check requirements
  • 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.
Focus your search
  • 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.
Make a good impression
  • 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.
Attend an information session

G+PS regularly provides virtual sessions that focus on admission requirements and procedures and tips how to improve your application.

Differential response of probiotics in perturbed pH and osmolality are correlated with genomic feature abundance (2022)

Probiotics have been identified as potential therapeutic vessels for numerous intestinal conditions, but we do not yet understand their ability to colonize a host, particularly one whose gut environment has been affected by disease. Physical factors are key in determining the ability of bacteria to survive and colonize within the gut and need to be investigated in the context of probiotic therapy. This project aims to characterize the strain-specific adaptability of commercially available probiotic strains to disease-relevant physical parameters – pH and osmolality. Different strains of lactic acid producing bacteria and Bifidobacterium spp. were isolated from ten commercially available probiotics and assessed for their growth in various pH and osmolality conditions and for their ability to impact their surrounding abiotic environment. We found that probiotic strains from the same phyla exhibit differential growth responses to high osmolality and low pH conditions, and we performed comparative genomic analysis to identify candidate genes involved in probiotic stress response. This study highlights the impact of biophysical parameters on commensal bacteria survival and helps to inform characteristics that are important for probiotic strains to establish sufficient viability in the dynamic gastrointestinal environment and will ultimately facilitate the development of other microbiota-based therapies.
