Congrats to Shaofei Zhang on successfully defending his thesis! He is the ninth PhD student to graduate from the group. Special thanks to jury members Prof. Abder Amgoune (Lyon), Prof. Tanja Gulder (Leipzig, via Zoom), and Dr. Morgan Donnard (Strasbourg) for being part of the jury, which was done partly in person and partly over Zoom. Best of luck in your return to China and in your next role!
