MIT Room 32G-844
I am an Edwin Sibley Webster Professor of
Electrical Engineering and Computer Science
Computer Science and Artificial Intelligence Laboratory (CSAIL).
I belong to the Computation Structures Group.
My research interests include computer architecture, computer security, VLSI design, computer-aided design, hardware validation, network router hardware, computer security, and computational biology.
One project I was involved with was building Aegis, a secure hardware processor that uses Physical Unclonable Functions (PUFs) to generate secret keys from chip fabrication variations. My research group has worked on trusted virtual computation and secure virtual storage as part of the Quanta Qumulus project at MIT.
My group has worked on novel on-chip networks and routing algorithms. We recently taped out EM2, a 110-core Execution Migration Machine, a 10mm x 10mm chip in 45nm technology. EM2 uses deadlock-free computation migration to provide a shared memory abstraction without requiring directories and uses an intelligent predictor to determine when to migrate computation versus data. Chips back in late 2013!
I am also involved in the Angstrom project. Angstrom is a proposed 1000-core self-aware processor. We built an Angstrom energy-aware processor tile in 0.18um with a LEON3 processor and energy monitors that allow software to precisely monitor energy consumption.
My research group is designing Ascend, a new type of secure processor that allows untrusted programs to compute on encrypted data from a client without leaking information about the data. Ascend uses optimized ORAM to obfuscate memory address patterns.
I am the Computer Science track coordinator of the MIT PRIMES high-school outreach program, a year-long program where high-school students are exposed to research and mentored by MIT students. I served as the chair of Area II (Computer Science Graduate Program) from June 2003 to November 2005, and as the Research Director of Architecture, Systems and Networking within CSAIL from September 2003 to October 2005. I served as Associate Head of the Department of Electrical Engineering and Computer Science with responsibility for Computer Science from 2005 to 2011.
