I am a senior principal researcher in the Office of the CTO, Azure for Operators at Microsoft. My research focuses on building trusted and secure systems, but I am interested in all aspects of systems research.

I am very proud when my research has impact in practice. Over the years, together with my colleagues, I have been fortunate to:

  • influence the DRAM industry to start addressing the threat of RowHammer attacks.
  • ship a cloud service used by 20+ million users.
  • build the reference implementation of the firmware TPM.
  • build one of the first face recognition-based payment systems, six years before Amazon Go was launched.

Prior to coming to Microsoft, I was a faculty member of the Computer Science Department at the University of Toronto. I received my Ph.D. from the Computer Science & Engineering department at the University of Washington. I am an ACM Distinguished Member.

The good folks at Microsoft Research recorded a podcast with me on RowHammer and wrote a blog post on my work and background.
