A randomly generated cubic surface with its real lines (mathematica notebook below )

bio/contact info:

I am an NSF Postdoctoral Scholar at Stanford University. In June 2017, I received my PhD from the University of Chicago under Matt Emerton. In July 2012 I received a joint master's degree from Leiden University and Universite Paris-Sud 11 through the ALGANT integrated masters course.

I am interested in arithmetic geometry, algebraic geometry, and number theory.

Office: 384-F (that means Building 380, fourth floor, office F. If I'm not there, say hello to Pablo!)

This is me in September 2016 on Maui. Unfortunately, you're more likely to find me in my office.

papers about things I still think about:

  1. A unipotent circle action on p-adic modular forms. Preprint.
    Comments, questions, and/or suggestions are very welcome! [Note that this is an updated version of a preprint that was earlier distributed under the name "the big Hecke action" and even earlier as "theta and the big Hecke action". Make up my mind, why don't I?]
  2. The p-adic Jacquet-Langlands correspondence and a question of Serre. arXiv:1806.06807.
  3. Overconvergent modular forms and the p-adic Jacquet-Langlands correspondence. University of Chicago PhD Thesis, 2017. pdf
    Some of the results of this thesis appear in "The p-adic Jacquet-Langlands correspondence and a question of Serre," above.
  4. Transcendence of the Hodge-Tate filtration. To appear, JTNB. arXiv:1610.05242.
  5. Motivic random variable and representation stability II: Hypersurface sections. arXiv:1610.05720. An updated version (will be updated on arXiv when final journal version is ready).
  6. Motivic random variable and representation stability I: Configuration spaces. arXiv:1610.05723.

Some of these are old and may be be quite rough, sorry!
