I am a second year PhD student of Prof. Littelmann in Cologne and my background is the representation theory of Lie algebras.
My current projects involve the study of toric and semi-toric degenerations of Grassmannians, the flag variety, and Schubert varieties using methods from combinatorics, cluster varieties, and tropical geometry. I would further like to understand connections to the theory of valuations, Newton-Okounkov bodies and mirror symmetry.

Alfredo Najera is coming to Cologne to give lectures on "Quivers with potentials in algebra and geometry", November 2/3/7. As part of the graduate school, lectures are open to everyone who is interested including all students and graduate students! Click here for all details.
