I coorganised Warsaw Summer School in Probability.

I am an assistant professor in the Faculty
of Mathematics, Informatics and Mechanics, University of
Warsaw.
I
was
a
post-doc
at
the Université de Genève working
under the supervision of prof. Yvan
Velenik.
Further, I was a post-doc at the Prob-Lab
working with dr Simon
Harris and prof. Andreas
Kyprianou.

My Ph.D. supervisor was prof. Tomasz
Bojdecki.

My email address is: pmilos (at) mimuw.edu.pl

I am interested in probability. More particularly in
stochastic
processes, stochastic models, branching processes, limit
theorems, problems arising in the mathematical physics. (e.g. surfaces
models, entropic repulsion
phenomenon etc).

I take interest also in machine learning and most particulary in reinforcement learning.

You can read about it in my papers. Most of them are available on
arXiv.

A wonderful movie
depicting the famous "sphere eversion".

Do you think that the
Möbius transform is difficult? Not at
all!

Surprisingly many extraordinarily intelligent people give
crappy
talks on conferences.

If you've never heard of Terrence Tao go here.
Later read
his amazing blog.

Do you know who your mathematical ancestor was. Or you
would like to
know that your grand-grand-...-grand supervisor was David
Hilbert ...

Well, I am not a Ph.D. student any more but the Ph.D. comics
still
amuses me.
