Jose Bastidas

PastoColombia

I am a postdoctoral fellow at the Laboratoire d’Algèbre, de Combinatoire et d’Informatique Mathématique (LACIM),

part of the Université du Québec à Montréal.

I am currently co-organizing the Séminaire du LACIM with Samuele Giraudo and Christophe Reutenauer. If you are planning to visit Montreal, and would like to give a talk in our seminar, contact me.

I obtained my Ph.D. at Cornell University, where I worked with Marcelo Aguiar. I previously obtained a MSc and a BSc degree in Mathematics at Universidad de los Andes (Colombia) working with Mauricio Velasco.

Research

My research interests lie in algebraic combinatorics. I am specially interested in the interplay between Hopf monoids in the category of Species and hyperplane arrangements.

See my papers on arXiv.

Upcoming talks

October, 2024. Michigan State University Combinatorics and Graph Theory Seminar.
