Laurin Brandner

I am Laurin, a third-year PhD student in the Networked Systems Group led by Prof. Dr. Laurent Vanbever. My main interest lies in the network stack of the end host. I extend it with eBPF, and accelerate it with things like AF_XDP and io_uring. This also includes network stacks for QUIC, which are typically not handled in the Linux kernel and thus need a bit more love.
