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 recent Notices of the AMS article. More details can be found on my research page.

Previously I was a CRM-ISM postdoctoral fellow at LaCIM UQAM (2019-2020) and 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.

I am currently taking graduate students. Please apply through our Department application process by the appropriate deadline and list me as a potential supervisor.

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.
