Research interests

My research exploits the structure of signals in the physical world and the flexibility of human perception to make computation more efficient.

Summary of Recent Research: My research focuses on designing hardware architectures, algorithms, and programming language constructs that permit as many errors as constraints of input signals or the consumers of the system’s output can tolerate. My research results range from printed circuit board and FPGA prototypes to proofs of bounds on properties of algorithms, programming language and compiler tools.

Prior to joining Cambridge in 2017, I was with MIT in Cambridge Massachusetts  (2014–2017). I completed my Ph.D. at CMU in 2007 in the lovely city of Pittsburgh. From 2008–2012 I was a permanent research staff member (RSM) at IBM Research in Zürich, and at Apple in Cupertino California from 2012–2014. Before graduate school, I spent several summers as an intern at Bell Labs in Murray Hill, NJ. At Bell Labs, I first spent two summers (1995, 1996) in the Microelectronics division with a group that designed ASICs for telephony applications. I then spent an extended co-op (1999) in the Lucent Bell Labs Data Networking division, in a project spun out of the UNIX group, doing work with the Inferno Operating System.
