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

Teaching and seminars.    Utrecht Staff colloquium.    Quarterly Topology and Geometry seminar.
From 2004 to 2007, I organized the first four Talbot workshops, with C. Douglas, J. Francis, and M. Hill.
In August 2010, I ran a workshop on Operator algebras and conformal field theory (i.e. conformal nets).
My ERC grant proposal is about the conjectural relationship between conformal nets and TMF.
It describes pretty well my research interests. Here it is: Part 1 (administrative) and Part 2 (math).

  • A K(Z,4) in nature: video
  • A partial construction of extended CFTs. On the same topic: one video... and four more videos.
  • My long-term project with Arthur Bartels and Chris Douglas is taking shape: here are the first, second, and third papers of a series of 5 papers on conformal nets.
  • Twelve videos on Quantum groups and 3-manifold invariants, with Chris Douglas.
  • The square root of a modular tensor category: video.
  • On various notions of tricategories, with Chris Douglas.
  • Orange peels, with Laurent Bartholdi.
  • On index of subfactors, with Arthur Bartels and Chris Douglas.
  • TMF and conformal nets, with Chris Douglas.
  • A page on the 576-periodicity of the free fremion, along with a video where I talk about this conjecture.
  • Conformal nets and local field theory, with Arthur Bartels and Chris Douglas.
  • A draft about Z/2-graded conformal nets and string structures, with Chris Douglas.
  • A draft on a model of K-theory via non-locally trivial vector bundles.

  • A lecture by Mike Hopkins on MString → tmf.
  • The n-dimensional cube recurrence, with David Speyer.
  • A model category for stratified spaces.
  • A picture of the sphere eversion
    Here's a picture indicating the ring structure of tmf  at p = 2, and here's a survey on π*(tmf) and on the Adams spectral sequence for tmf.
    Here's a list of typos and comments for A. Wassermann's article Operator algebras and conformal field theory.

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

  • An action of the cactus group.
  • On the homotopy theory of orbispaces, with David Gepner.
  • CFT's associated to non-effective orbifolds, with Simeon Hellerman , Tony Pantev, Eric Sharpe, and Matthew Ando.
  • The periodicity of the bounded octahedron recurrence.
  • How to integrate L-infinity algebras. This 3 page abstract focuses more on the String group.
  • Gerbes on C/Z3, with Giovanni Felder, Carlo Rossi, and Chenchang Zhu.
  • 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.

  • My thesis (2005) is on orbispaces.
  • With Pavel Etingof, Eric Rains, and Joel Kamnitzer on the cohomology of the real locus of \bar Mo,n.
  • With Laurent Bartholdi and Volodia Nekrashevych on groups and automata .
  • With Joel Kamnitzer on a commutor for crystals, and on gl(n)-crystals.
  • With Tara Holm and Megumi Harada on T-equivariant generalised cohomology of G/P.
  • A picture of the subalgebra A(2) of the Steenrod algebra.

    I was also a grad student of Allen Knutson at Berkeley.

  • On presentations of non-effective orbifolds, joint work with David Metzler.
  • On a definition of orbifolds that uses the Borel construction.
  • On a convexity property of amoebas of algebraic varieties.
  • Here's my qual syllabus.

    Even before, I was an undergraduate in Geneva.

  • My undergraduate thesis with Vaughan Jones on the Ising model.
  • On a q-analogue of the notion of arithmetic polynomial.
