C.V. (last updated in 2019)

Publication list.    Difficult to find.    Algebraic topology conferences.    Operator algebra conferences.    Mathematical physics conferences.

Teaching and seminars.   
As an effort to raise people's attention on the issue of climate change (and the responsibility that we all share as frequent conference-goers) and illustrate the possibility of alternative conference formats, I have recently organised a couple of double conferences. A double conference is a more eco-friendly format (less air traveling!) where the event takes place is two different locations, connected by live video stream.

    In August 2010, I ran a workshop on Operator algebras and conformal field theory (i.e. conformal nets).

    Many years ago, I was a post-doc at Münster, in the topology group of Wolfgang Lück.

  • Some notes on CW-orbispaces, and some on orbivariant K-theory.
    Here's a one page handout on stacks.

    Before, I was a grad student of Mike Hopkins at MIT.
