The workshop was really great and productive for me. I got the chance to speak with very good mathematicians in my research area and to develop some new ideas. In particular, I had the occasion to speak with Yuval Peres about the Poisson boundaries of lamplighter random walks on oriented trees, and this may result in a potential collaboration and an eventual research visit to Microsoft Research in Spring 2016. Needless to say that Banff is a wonderful place for research and for vacation. I am looking forward to the next meeting of this type in Banff. The organizers did a really good job in organizing this meeting!
