Research Profile

My research is at the interface of the Langlands correspondence with arithmetic algebraic geometry. At the heart of the Langlands program lies reciprocity, the conjectural correspondence between Galois representations and automorphic forms. Progress in the field has historically required the combined forces of many areas of mathematics and continues to do so. In my work, I approach the correspondence from several different directions, combining number theoretic techniques, such as p-adic interpolation, with arithmetic geometry (perverse sheaves, p-adic Hodge theory), harmonic analysis (the trace formula) and representation theory (the theory of types). In joint work with Emerton, Gee, Geraghty, Paskunas and Shin, I constructed a candidate for the p-adic local Langlands correspondence for GL_n over a p-adic field and I showed that this construction recovers the p-adic local Langlands correspondence for GL_2(Q_p); this led to proving some new cases of local-global compatibility. In joint work with Levin, I showed that the moduli space of Kisin modules with tame descent data is smoothly equivalent to a local model of a Shimura variety with parahoric level structure. In joint work with Scholze, I showed that the cohomology of compact unitary Shimura varieties is torsion-free and concentrated in the middle degree, when localized at a sufficiently generic system of Hecke eigenvalues.

My future research is focused on extending, in joint work with Scholze, the results about torsion in the cohomology of compact unitary Shimura varieties to the non-compact case. This presents significant difficulties and requires new ingredients, both from the point of view of arithmetic geometry (one needs to work with both minimal and toroidal compactifications of Shimura varieties) and from the point of view of the trace formula. I am also working on understanding consequences of such a result about non-compact Shimura varieties for the Galois representations corresponding to torsion classes in the cohomology of locally symmetric spaces. I am particularly interested in local-global compatibility at l=p and applications to modularity or potential modularity of Galois representations. Furthermore, I am interested in discovering other consequences of the fact that Shimura varieties with infinite level at p are perfectoid and in studying moduli spaces of Galois representations via the moduli space of Kisin modules.
