Del Pezzo surfaces are fundamental objects in algebraic geometry that have rich combinatorics. Smooth cubic surfaces, for example, are del Pezzo surfaces of degree 3. The moduli space of (marked) del Pezzo surfaces of degree 9-n can be viewed as a configuration space of n points in general position in the projective plane. In this talk I will mostly focus on the case of cubic surfaces; I will analyze individual surfaces as well as their moduli and show that they are positive geometries. This is joint work with Nick Early, Alheydis Geiger, Marta Panizzut, and Bernd Sturmfels.
