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.

Traffic congestion control: a comparative analysis of tradable permits and road tolls (2021)

Tradable permits have been proposed in the literature as a tool for controlling road traffic congestion. Unlike with tolls, travelers in aggregate do not incur net out- of-pocket costs if permits are distributed free. Moreover, if travel conditions do not change, tradable permits can be designed to support the same traffic flows as tolls. However, the two instruments are no longer equivalent if conditions fluctuate and neither permit quantities nor toll levels can be adjusted accordingly. In this thesis, we evaluate the efficiency of tradable permits and road tolls in controlling traffic congestion during a morning peak travel period on a stylized urban road network with daily commuters who travel from their homes to their workplaces. We compare the economic efficiency of the two instruments when road link capacities are susceptible to reductions due to incidents, bad weather, road repairs or other shocks. We apply the dynamic traffic network simulator METROPOLIS in which travelers make mode, departure time and route choice decisions. Fixed permit quantities and toll levels are chosen to control the number of vehicle trips crossing a cordon into the city centre with the goal of maximizing welfare defined by expected social surplus. Simulations are performed for a range of scenarios in which road capacities are correlated or uncorrelated, and suffer reductions of varying magnitude. Most of our analysis suggests that road tolls outperform tradable permits. However, in some instances tradable permits do better; in particular, when the road links that bypass the centre of the network experience capacity fluctuations.
