Mika Göös
Sup. I am an assistant professor at EPFL in the Theory Group.
Previously, I was a post-doc at Stanford, Princeton IAS, and Harvard. I completed my PhD at University of Toronto under the scrutiny of Toniann Pitassi. I obtained my MSc from the University of Oxford and my BSc from Aalto University.
