Teaching


  • In Spring 2019, I will be teaching "Topics in Number Theory" at the University of Amsterdam. Course materials can be found on Canvas.
  • In Spring 2018, I will be teaching "Vector Calculus" at AUC. Course materials can be found on Blackboard.
  • In June 2015 I gave a few lectures to Masters students in Padova about fundamental groups in algebraic geometry. You can find the lecture notes here.
  • In Autumn 2014 I organised part of a graduate course at the London School of Number Theory and Geometry, the topic being the Weil conjectures and Betti numbers of moduli spaces. You can find the notes to my lectures on Weil cohomology theories and zeta functions here, and James Newton's notes from his lecture on Monsky Washnitzer cohomology here.
