My research concerns the mathematical aspects of classical and
quantum field theory, with a particular emphasis on gravity (general
relativity). On the physics side, I am interested in the formulation of
quantum gravity as a field theory, focusing on the problems of causality
and observables in quantum gravity. I am also interested in various
mathematical topics that play a role in my work, including the
following: geometry of PDEs, jet bundles, conservation laws, symmetries,
symplectic and Poisson geometry, homological algebra, supergeometry,
infinite dimensional analysis, synthetic differential geometry, category
theory.
I am a coorganizer of the PragueHradec Králové seminar on Cohomology in algebra, geometry, physics and statistics
(,
recorded lectures).
In 2017, I have helped organize the minisymposium QFT
Day in Milan: mathematical aspects of renormalization (poster PDF, SVG).
In 2014–2015, I had helped organize the Mathematical Physics Seminar in Trento.
During 2016–2019 it was reprised here here.
