Hi, I'm an associate professor in the College of Information and Computer Sciences at the University of Massachusetts, Amherst. I'm a member of the theory group and my research is in algorithms and complexity. Specific topics include processing massive data sets and data streams, clustering, approximation algorithms, coding and information theory. Feel free to check out my research papers or cv.

Prior to UMass, I spent a great couple of years at Microsoft Research (Silicon Valley) and the Information Theory and Applications Center at UCSD. In 2007, I received my Ph.D. from the University of Pennsylvania. During graduate school, I spent a summer at DIMACS and three summers at the Fundamental Maths Department at Bell Labs. In the dim and distant past, I received the Certificate of Advanced Study in Mathematics (2001) and a B.A. in Mathematics (2000) from the University of Cambridge.

Here's the text of a short bio and a photo.

But a cloud minus a sailboat
Have no idea what it is."
