Introduction

I am a senior principal researcher in the Office of the CTO, Azure for Operators at Microsoft, specializing in the creation of trusted and secure systems. My interests span all aspects of systems and networking research.

My research is driven by its practical impact. Throughout my career, I have, along with my colleagues, managed to:

  • Influence the DRAM industry to address the threat of Rowhammer attacks.
  • Develop and launch a cloud service used by 20+ million users.
  • Create 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 joining Microsoft, I served as a faculty member in the Computer Science Department at the University of Toronto. I earned my Ph.D. from the Computer Science & Engineering department at the University of Washington, and I am an ACM Fellow.

Microsoft Research has featured me in a podcast on Rowhammer and published a blog post detailing my background and research. I also maintain a page with brief articles on various topics related to Rowhammer.
