My name is Anna Rodriguez Rasmussen, I am currently a Postdoc at the University of Cologne with Sibylle Schroll. I obtained my PhD in May 2026 from Uppsala University, my supervisor was Julian Külshammer.
My interests include:
quasi-hereditary algebras and their Borel subalgebras
A-infinity algebras and applications thereof in representation theory
exact categories
