I'm a PhD student at the Department of Mathematics, University of Toronto.

Previously I studied mathematics, physics and computer science at University of Warsaw, where I obtained M. Sc. degree in mathematics.

My main interests are geometric group theory and discrete probability. I'm also interested in theoretical computer science, combinatorics and theoretical physics.

comment Nonmonotonicity of expected distance of a random walk
A nice example. But somehow this is still not what I had in mind, see the edit in the question.

comment Can a tree cover a finite graph with arbitrary large girth?
I don't see how the group $G$ enters the picture here.

Thanks for posting this, it's quicker and tidier than the explicit calculations I wrote down in my answer
