I am a differential geometer interested in the interplay between geometry and dynamics. I enjoy exploring how geometric structures help us understand the behaviour of mechanical systems, from Hamiltonian dynamics to dissipation and nonequilibrium thermodynamics.
Poisson geometry is a central thread in my work, connecting my interests in Nijenhuis and Dirac structures, pseudo-Riemannian geometry, and Lie theory. I also like exploring how these ideas carry over to discrete mechanics and structure-preserving numerical methods.
