My aim is to use algebraic geometry to establish higher reciprocity laws, which serve as a bridge between the field of arithmetic and the theory of automorphic forms. I am interested in Shimura varieties and their local variants  from the point of view of constructing interesting Galois representations, of identifying algebraic cycles on them, and of studying their deformations.


Former Research Area D My contributions in this RA can be grouped into two main directions. First, there has been substantial progress in my joint project with S. Kudla in giving arithmetic interpretations of the Fourier coefficients of Eisenstein series. The case of the modular curve with no ramifications has been completely solved and is documented in the monograph [1] with S. Kudla and T. Yang. The basis for our results are the theory of Gross/Keating. In my seminar we elaborated an uptodate account of this theory. Recently Kudla and I started to develop an analogous theory for the Shimura varieties associated to unitary groups [2].
Second, in the direction of Shimura varieties, I published a monograph [3] on the theory of period spaces with Dat and Orlik. It leads from the elementary theory of filtered vector spaces to the first published account of the determination of the EulerPoincaré characteristic of adic period domains.  Former Research Area E I developed further, in collaboration and close contact with G. Pappas and B. Smithling, the theory of local models of Shimura varieties. The paper [4] treats the case of ramified unitary groups, and states the highly relevant “coherence conjecture” which has been proved recently in spectacular work of X. Zhu. Smithling has proved the topological flatness conjecture of loc.cit.
Another topic developed in [5] is the theory of bundles on algebraic curves. Some conjectures of loc. cit. have been proved by J. Heinloth.  Former Research Area F I developed with G. Pappas [6] a theory of algebraic loop groups, generalizing the theory of Faltings to the nonconstant, or twisted, case. In [7], Pappas and I gave a new framework for moduli spaces of Kisin modules it coefficient spaces, with possible applications to deformation problems of Galois representations.  Research Area DE
