Recruitment

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

Check requirements
  • Familiarize yourself with the 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 our graduate degree program listings 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.
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.
  • 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 peek someone’s interest.
  • Provide documents that can help the faculty member gauge interest in you as a potential student. This could be a Statement of Intent, a Writing Sample, a list of publications or research endeavors.
  • 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.
