I am a post-doctoral researcher in the combinatorics group of IRIF. I am supported by the ERC Starting Grant CombiTop: New Interactions of Combinatorics through Topological Expansions, awarded to my mentor Guillaume Chapuy. In 2017 I got my PhD at the University of Minnesota, under the supervision of Vic Reiner. You can call me 'Theo'.
If you are looking for my cousin, the physicist Theodosios G. Douvropoulos, you should look here.
I enjoy thinking about combinatorial phenomena that have generalizations in the world of reflection groups; what is usually called, Coxeter Combinatorics. This is a diverse world, whose residents -the complex reflection groups- albeit objects easy to grasp, can nonetheless reveal deep connections between algebraic, topological and geometric concepts.
