Modular forms, which are my main area of research, can be seen as part of both the theory of automorphic forms and of moduli spaces (Research Area DE), but are also of great importance in many parts of quantum field theory and string theory (Area C). My research in the last years has touched all these aspects, two examples being my work with Dabolkar and Murthy on applications of ''mock modular forms'' (as developed by my then student Zwegers, myself and others) to the string theory of black holes and my recent work with Möller on applications of the theory of modular and quasimodular forms to Teichmüller curves and to moduli spaces of flat surfaces. With Garoufalidis I have also been studying the arithmetic of quantum invariants of knots: we proved some cases of the conjectured ''quantum modularity'' properties of Kashaev invariants that I had discoved experimently ten years ago and, in joint work with Frank Calegari, found a construction of algebraic units from classes in algebraic Ktheory having as an unexpected consequence a proof of Nahm's conjecture relating modularity to algebraic Ktheory.
Recently I have become interested in the arithmetic and topology of differential equations (the subject of the ''Hirzebruch Lecture'' that I gave at the ECM 2016). Together with Vasily Golyshev, with whom I have already published one paper on the subject (proving the socalled ''Gamma Conjecture'' for all rank one Fano 3folds) and others (in particular Masha Vlasenko and Spencer Bloch), I am studying the relation of ''motivic gamma functions'' (a kind of Mellin transform of solutions of PicardFuchs differential equations) and Hirzebruchlike characteristic classes of algebraic varieties. In other directions, I am studying together with Lin Weng the properties of the ''higher rank zeta functions'' of curves over finite fields that he defined some years ago (in particular, we proved the Riemann hypothesis for the genus one case and are working on the general case), and am also working with T. Ibukiyama to extend our theory of ''higher spherical polynomials'' to a theory of higher spherical functions. Finally, in collaboration with Martin Möller and others (recently Di Yang and Boris Dubrovin), we are extending our earlier work on combinatorial aspects of moduli spaces (Hurwitz numbers, graph counting, generalizations of the BlochOkounkov theorem, ...).
