About me Research Teaching Other


Masters Theses

At the moment I am supervising Xenia Flamm and Anna Ribelles as Masters students. I am not accepting additional students this semester. My past Masters students are Guo Sheng Ho and Jose Pedro Quintanilha.

Wintersemester 2017/18

Class on Gromov's Polynomial Growth Theorem

I will teach a course on Gromov's polynomial growth theorem, offered as Selected Topics in Geometry (V5D4). This will be an (informal) continuation of my course in geometric group theory. This means that the course will deal with a more advanced topic in geometric group theory, but the topics covered during my V5D3 are not required prerequites.

Seminar on Property (T)

Joint with Bram Petri I will be running a seminar on Kazhdan's property (T), offered as Graduate Seminar on Advanced Geometry (S4D3). See here for an annoucement with summary and talk details.

Assigned Talks (dates might not be final)

Sommersemester 2017

I am teaching a course on Geometric Group Theory (V5D3). Here is a brief course announcement.
During the first half, we were (roughly) following the book "Trees" by Serre. In the second half, one useful source are the notes by Brian Bowditch on geometric group theory.

There are no problem sessions, but there will be (irregular) problem sets here. Please try to solve them -- they are excellent preparation for the exam! I try to be very careful typesetting these, but there may always be typos. If you feel that an exercise contains a mistake, please email me.

Wintersemester 2016/2017

In Wintersemester 2016/2017, I am organizing a Graduate Seminar on Advanced Geometry (S4D3) on Heegaard splittings and the Curve Graph. See the announcement and talk details here. The preliminary meeting took place Tuesday, July 19, 14:00-15:00 (N0.003). The seminar will take place on Wednesdays, 16:00-18:00 (N.008).

Assigned Talks (dates should be final)

Sommersemester 2016

During Sommersemester 2016, I am teaching a course on Teichmüller theory. See here for the announcement.

Wintersemester 2015/2016

In the Wintersemester 2015, I am co-organizing (with Ursula Hamenstädt) the Graduate Seminar on Advanced Topology (S4D4) on group cohomology and bounded cohomology. See here for a summary of topics.
