Joseph Muller is a postdoctoral fellow at the National Center for Theoretical Sciences (NCTS). His mentor is Dr. Chia-Fu Yu.

He received his PhD degree from Sorbonne Paris North University in 2023, under the supervision of Prof. Pascal Boyer and Prof. Naoki Imai. Before joining NCTS, he was a JSPS postdoctoral fellow at the University of Tokyo.

His research theme is about number theory and arithmetic geometry. More specifically, he is interested in the cohomology of Shimura varieties, and the arithmetical and geometrical aspects of their supersingular locus. His research aims at understanding some links between Shimura varieties and Deligne-Lusztig theory.
