I organize Waterloo’s Algebraic and Enumerative Combinatorics Seminar.
In Fall 2021 I am teaching MATH 239 and CO 330
Analytic Combinatorics in Several Variables
I am a longterm 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.
