Teaching and seminars.   
From 2004 to 2007, I organized the first four Talbot workshops, with C. Douglas, J. Francis, and M. Hill.
Here's a pdf of a non-final version of my book on TMF, jointly edited with Chris Douglas, John Francis and Michael Hill.
In August 2010, I ran a workshop on Operator algebras and conformal field theory (i.e. conformal nets).
blue = on the ArXiv. pink = not on the ArXiv.
  • On the relationship between conformal nets and factorization algebras.
  • Planar algebras in braided tensor categories, with Dave Penneys and James Tener.
  • The 576 periodicity of Majorana fermions: slides
  • The classification of chiral WZW models by H4(BG,ℤ).
  • Some examples of Stolz-Teichner cocycles.
  • A note about the definition of modular functor used by Andersen and Ueno.
  • The first examples of categorified von Neumann algebras, with Dave Penneys.
  • On a notion of categorified trace, with Dave Penneys and James Tener.
  • The value of Chern-Simons theory on a point, along with a video.
  • The notes of my Berkeley Chern-Simons lectures, handouts 1 2 3.
  • Course notes on CFT (Berkeley graduate course, Spring 2014).
  • 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, third, and fourth 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.

  • 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.
  • My ERC grant proposal about the conjectural relationship between conformal nets and TMF: Parts 1, 2.
  • 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.
  • On String orientations, with Chris Douglas and Michael Hill.
  • A lecture by Mike Hopkins on MString → tmf.
  • The n-dimensional cube recurrence, with David Speyer.
  • A model category for stratified spaces.
  • A fusion category generated by two objects related to the Dynkin diagrams D10 and E7. 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.

    Many 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.
