The workshop on quasi-isometries and low dimensional topology was very interesting. I had some discussions with colleagues that I do not meet so often in a quiet atmosphere. I think these discussions will lead to some new results and maybe also to some new collaboration. The whole area of geometric group theory is very active and there are many meetings. However, I found this small conference particularly good.

The BIRS workshop on Quasi-isometric rigidity provided me with an excellent opportunity to meet and communicate with leading mathematicians in my field of research. During the five days workshop, I received comments and suggestions on my research projects that will have a significant impact in my future work.
