My name is Philippe Tranchida and I am currently holding a researcher position at the MPI in Leipzig in the non-linear algebra group. I obtained my PhD in mathematics at KAIST, in Daejeon, Korea, under the supervision of professor Harry Hyungryul Baik. Before that, I obtained my bachelor and master degree from ULB in Brussels, Belgium. My master degree thesis was supervised by professor Dimitri Leemans. Starting junuary 2026, I will hold a postdoctoral position as an FNRS chargé de recherche at the ULB, in Brussels.
