Alekos Robotis

I am an NSF postdoctoral fellow at Columbia University interested in derived and triangulated categories and moduli spaces in algebraic geometry, with a particular emphasis on Bridgeland stability conditions. In the coming academic year, I will be a postdoctoral researcher at Imperial College London working in the research group of Soheyla Feyzbakhsh.

In May of 2025, I completed my PhD at Cornell University working under the supervision of Daniel Halpern-Leistner. In the fall of 2025, I co-organized the postdoc algebraic geometry seminar at Columbia with James Hotchkiss.
