The paintings in the above photo are two of the larger ones from Josef Alber's Homage to the Square series and belong to the Neue Nationalgalerie, Berlin.

My work

My mathematical interests include homological algebra and category theory ((co)homology of algebraic structures, Hochschild and cyclic (co)homology, E_n-algebras, monoidal categories, operads), noncommutative geometry (spectral triples, residue cocycles, covariant differential calculi), and the theory of Hopf algebras and related structures (Yetter-Drinfel'd modules, quantum homogeneous spaces, Lie-Rinehart algebras, racks, Hopf algebroids, Hopf monads).
