Djordje Radicevic is a postdoc at Brandeis University. He obtained his Ph.D. from Stanford University under the supervision of Stephen Shenker and was a postdoc at the Perimeter Institute for Theoretical Physics before joining the Collaboration. He is interested in basic questions concerning quantum field theory: What are the possible fundamental degrees of freedom? How can they be related to each other via dualities? And how are these basic properties reflected in the quantum theories we use in our everyday lives?
