Birational geometry of algebraic varieties
Birational geometry has seen tremendous advances in the last two decades. This talk is a gentle introduction to some of the main concepts and recent advances in the field.

Dynamics, numerical analysis and some geometry
Geometric aspects play an important role in the construction and analysis of structure-preserving numerical methods for a wide variety of ordinary and partial differential equations. Here we review the development and theory of symplectic integrators for Hamiltonian ordinary and partial differential equations, of dynamical low-rank approximation of time-dependent large matrices and tensors, and its use in numerical integrators for Hamiltonian tensor network approximations in quantum dynamics.
