Boris Köpf



I am a researcher in the Confidential Computing group at Microsoft Research Cambridge, working on techniques for tracking information flow in microarchitecture and machine learning systems. Prior to joining MSR in November 2018, I was a tenured faculty at the IMDEA Software Institute, a postdoc at the Max Planck Institute for Software Systems, and a Ph.D. student at ETH Zurich.
