Christian Matt
I am a research scientist at Primev. Previously, I was a senior researcher at Concordium and a postdoctoral scholar at the University of California, Santa Barbara, supervised by Huijia Lin. Before joining UCSB, I completed my PhD in computer science at ETH Zurich under the supervision of Ueli Maurer, and my undergraduate studies at Karlsruhe Institute of Technology (KIT).
