## Welcome

Feel free to look around these pages, perhaps you'll find something you like.

My mathematical interests mainly concern algebraic combinatorics, in particular combinatorial and topological aspects of partially ordered sets and reflection groups. My research statement may provide more details.

Also, here is my CV and a copy of my thesis.

If you're into bijections, take a look at sequence A215582. It counts the number of mergings of two n-antichains. The proof of this fact uses generating functions, but I don't know of a bijective proof.

A280891 is another sequence that I've contributed to the OEIS. It counts certain noncrossing partitions, and thanks to Joel Lewis we now have a formula; it is essentially a difference of Catalan numbers.
