Research themes

Cohomology

Arithmetic geometry and cohomological constructions

Poincaré bundles, Eisenstein and polylogarithmic classes, and their motivic, syntomic, de Rham, and étale realizations, with applications to arithmetic invariants and special values.

p-adic theory

p-adic Fourier theory and arithmetic distributions

Integral p-adic distributions, Fourier transforms, Hecke correspondences, norm-compatible classes, and their relation to Iwasawa-theoretic constructions and p-adic L-functions.

Deformation theory

Formal groups and integral deformation theory

Formal groups, finite subgroup schemes, deformation spaces, and Witt filtrations measuring integral incidence and congruence phenomena. I am also interested in connections with chromatic homotopy theory.

Integral trace duality and the Witt filtration on Lubin–Tate space

Andrea Taccani, 2026. arXiv:2610.18246.

The paper identifies Rezk's Witt filtration with the divisibility filtration of integral trace pairings on subgroup algebras. It derives a recursion for the filtration, computes the cokernel of the universal source trace pairing, and studies integral traces along two-step isogeny flags.

Master's thesis · 2026

Poincaré Theta Distributions along Ordinary p-Power Isogenies

My master's thesis studies theta distributions obtained from the Poincaré bundle along ordinary p-power isogenies, together with the underlying biextension geometry, distribution relations, and p-adic integral structures.
