I am a Postdoctoral
Research Fellow at the University of Oxford.
I will move to Polish Academy of Science in Warsaw (Poland) in the fall 2016.
I have started a blog on adic spaces.
Research interests
Galois representations, automorphic forms, Shimura varieties, Langlands program, padic cohomology theories, adic and perfectoid spacesPreprints and publications
 Overconvergent modular forms and perfectoid Shimura curves (with David Hansen and Christian Johansson), preprint 2015, submitted
 An adjunction formula for the EmertonJacquet functor (with John Bergdall), preprint 2015, submitted
 Ordinary representations and companion points for U(3) in the indecomposable case (with John Bergdall), preprint 2014
