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 take great pride in my research when it has a practical impact. 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.
I also maintain a page with brief articles on various topics on Rowhammer.
In the cloud, per-VM hardware resources are strongly isolated from one another
except for DRAM!
Our SOSP 2023 paper
shows how to accomplish per-VM DRAM isolation using DRAM subarrays,
a DRAM-internal architectural block.
recordings are now available online for everyone to watch!
I asked ChatGPT to create a bio for myself. I found it very amusing. It lists several awards
that I never
received, but it falls short from going all out and claiming I won the Turing Award. :-)

I was awarded JEDEC Chairman of the Board Award "in recognition of row hammer mitigation and
standardization support in JC-42". While my name is on the award, this award should go to two groups:
(1) to the many in JEDEC who have been working tirelessly on fixing Rowhammer, and (2) to all
researchers who have been working on both attacks and defenses.
