Martin Szyld

Welcome to my home page! Last updated on Nov 4, 2020. I'm currently an AARMS postdoctoral fellow at Dalhousie University, please visit my home page there for further updates.

Research Interests

  • Category theory and its applications. In particular the extension to higher category
    theory of basic categorical concepts and results.
  • Representation theory. In particular Galois and Tannaka theories, especially for topos.


that's me!
