About
I am a scientist at Azure Research (formerly the Confidential Computing group at Microsoft Research), where I work on
techniques for tracking information flow in microarchitecture and machine learning systems.
Prior to joining Microsoft 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.
