Changying Ding


Starting July 2023, I will be working with Sorin Popa and Dimitri Shlyakhtenko as a Hedrick Assistant Adjunct Professor at UCLA. I finished my Ph.D. at Vanderbilt University under Jesse Peterson in 2023. My CV is available here.

I am interested in operator algebras, geometric group theory, ergodic theory and operator space theory.
