I’m an assistant professor in the Department of Combinatorics and Optimization at the University of Waterloo, interested in leveraging computational algebraic geometry, analysis, and topology to create effective tools for combinatorics, computer science, and mathematics.

A short overview of some of my research interests can be found in this Notices of the AMS article or this reading course outline. More details can be found on my research page.

Previously I was a CRM-ISM postdoctoral fellow at UQAM (2019 – 2020) and a postdoc at the University of Pennsylvania (2017 – 2019). I received doctorates from the École normale supérieure de Lyon and the University of Waterloo in 2017.

I organize Waterloo’s Algebraic and Enumerative Combinatorics Seminar.

In Fall 2021 I am teaching MATH 239 and CO 330

I am currently hiring a postdoc to work on problems in analytic combinatorics in several variables. Details can be found in the application on MathJobs – if you are interested please complete that application by December 20, 2021.

I will be taking at least one Masters and/or PhD student for the Fall 2022 semester. If you are interested please apply through our department’s process and list me as a potential supervisor (note the February 1 deadline).

Analytic Combinatorics in Several Variables

I am a long-term organizer of the analytic combinatorics in several variables project and am involved in two textbooks on the topic.

  • An Invitation to Analytic Combinatorics: From One to Several Variables
    S. Melczer.
    Springer Texts & Monographs in Symbolic Computation, 2021.
    Book webpage

  • Analytic Combinatorics in Several Variables, 2nd Edition
    R. Pemantle, M. C. Wilson and S. Melczer.
    Cambridge Studies in Advanced Mathematics.
    Expected late 2021 or 2022
    ACSV project webpage

The first book is an introductory treatment, suitable for students and those new to the area, while the second is a more advanced treatment making extensive use of homology, multivariate residues, and similar constructions.
