Kabeer Manali Rahul

I am currently a postdoc at Bonn where my mentor is Daniel Huybrechts. Before that, I did my PhD at the Australian National University under the supervision of Amnon Neeman. Most of my research is on derived and triangulated categories in the context of algebraic geometry. Recently, I have been working with derived categories arising in noncommutative algebraic geometry too.
