Before graduating in August 2011, I was a Ph.D. student at Northwestern University in the Electrical Engineering and Computer Science department. My advisor was Professor Peter Dinda, and I worked on mobile systems, with an emphasis on acoustic sensing. My other interests include music technology, operating systems, electronics design automation, optimization algorithms, Internet telephony, embedded systems, architectural acoustics and high-performance computing.
My graduate work was funded by Northwestern University through various fellowships and through my advisors' National Science Foundation grants.
