The Department of Combinatorics and Optimization at the University of Waterloo invites applications from qualified candidates for one 2-year postdoctoral fellowship appointment in graph theory under the joint supervision of Dr. Luke Postle (University of Waterloo) and Dr. Michelle Delcourt (Toronto Metropolitan University). The primary focus of this position is in the area of probabilistic and extremal design theory (broadly construed to include topics such as Hamilton cycles, graph/hypergraph decompositions, embeddings, matchings, Latin squares, Steiner systems, etc.); the postdoctoral fellow will be expected to work on joint projects that broaden and extend the recent progress of Professors Delcourt and Postle in this area.
Expertise in extremal combinatorics, probabilistic combinatorics, or structural graph theory is desired. In particular, familiarity with some (or all) of the following topics is preferred: designs, absorbers, graph decompositions, the probabilistic method, graph coloring, nibble, concentration inequalities. Familiarity with the following will also be considered desirable: graph algorithms, discharging, optimization, spread distributions, expanders, hypergraph containers, Ramsey theory, differential equation method, Dirac-type problems.
A Ph.D. degree and evidence of excellence in research are required. Successful applicants are expected to maintain an active program of research. The annual salary is $65,000. In addition, a travel fund of $3000 per year is provided. The effective date of appointment is September 1, 2026 - August 31, 2028. However, dates are negotiable. There is a possibility for a third year extension subject to productivity and funding. This position is physically based at the University of Waterloo, and as this is a research focused position, there is no required teaching load for this position.
Interested individuals should apply using the MathJobs site (https://www.mathjobs.org/jobs/list/27648). Applications should include a cover letter describing their interest in the position, a curriculum vitae, a research statement, and at least three reference letters.
Inquiries may be addressed to Luke Postle, Full Professor, Department of Combinatorics and Optimization, University of Waterloo, Waterloo, Ontario, Canada N2L 3G1. The deadline for application is December 15, 2025.

Canada Excellence Research Chair (CERC), Associate or Full Professor in Quantum Information
Date Posted: August 27, 2025
Located in the heart of Waterloo Region, the University of Waterloo is at the forefront of innovation and home to world-class research and inspired teaching. The Institute for Quantum Computing, in collaboration with the Faculties of Mathematics and Science, is seeking exceptional scholars and researchers to take up a position as a Canada Excellence Research Chair (CERC) in the strategic priority area of Quantum Information. The CERC program was established to offer Chairs valued at $500,000 or $1,000,000 per year, for a total of $4,000,000 or $8,000,000 over eight years. The University of Waterloo is proceeding with nominations at the $500,000 level, with funds allocated towards the Chair’s salary and research expenses.
Candidates will have a PhD or equivalent with a relevant professional designation or licensure, a requirement of the University of Waterloo. A global research leader with evidence of an exceptional research program that has made a major societal impact, the candidate will propose an innovative program of high-quality research that includes collaboration with researchers in closely related fields and supervision of graduate students. They will also teach at the undergraduate and graduate levels (a reduced teaching assignment will be in place during the term of the Chair) and provide service to the unit. Applicants whose research aligns with the University’s Strategic Plan and Research Strategic Plan and the Government of Canada priorities are preferred. The search is open to all areas of quantum information related to the goals and ongoing research at IQC. We are especially interested in candidates working in:
• Quantum Error Correction,
• Quantum Networking,
• Interface Theory/Experiment,
• Applied Quantum Algorithms, and
• Quantum Materials/Devices.
The role includes appointment to a full-time tenured or tenure-track position at the rank of Associate or Full Professor within the Faculty of Science or Mathematics, along with membership in IQC. Specifically, this position can be held in any of the following departments and schools connected to IQC: Applied Mathematics, Pure Mathematics, Combinatorics and Optimization, Computer Science, Chemistry, and Physics & Astronomy. IQC membership is renewable and comes with research space and a stipend. Information about research at IQC can be found at https://uwaterloo.ca/institute-for-quantum-computing/research. All CERC appointments are subject to review and contingent upon approval by the CERC Secretariat (results expected January 2027). The salary range for the position will depend upon the rank (i.e., Associate Professor, Professor).
Eligibility
Candidates should be at the rank of Full Professor or be an Associate Professor who is expected to be promoted to the rank of Full Professor within one to two years of the nomination. Alternatively, if from outside the academic sector, nominees must possess the necessary qualifications to be appointed at these levels. The CERC program imposes no restrictions on nominees regarding nationality or country of residence. Researchers who hold a full-time academic appointment at another Canadian institution are eligible, but should they be nominated, the University will be required to demonstrate the net benefit to Canada in moving the researcher from one Canadian institution to another.
At Waterloo, it’s recognized that career interruptions can have an impact on research achievements. Applicants are encouraged to explain further how this may affect them in their application; this information will be taken into careful consideration during the assessment process. Contact the Office of Research for full CERC information, including further details on eligibility criteria.
How to apply
Applications received by September 30, 2025, will be given full consideration. However, applications will continue to be reviewed until the position is filled. Apply in confidence with a curriculum vitae, cover letter, research statement, teaching dossier, and up to five sample research outputs. Three letters of reference will be requested for applicants invited for an interview. If applicable, applicants are also invited to submit an optional letter or oral statement of support from the individual’s community that describes the individual’s involvement/role within the community, or a statement of lived experience. Send application packages to: https://uwaterloo.ca/institute-for-quantum-computing/research/available-positions.
All applicants to this CERC opportunity are required to self-identify using the self-identification applicant survey.
