Pedro Montero

I am mainly interested in birational geometry. More precisely, in asymptotic invariants and positivity in algebraic geometry (such as Newton-Okounkov bodies) and the use of techniques from the Minimal Model Program to the classification of algebraic varieties (e.g. Fano varieties). I am also interested in algebraic group actions on algebraic varieties.

Here you can find my research articles.
