Background:

Academic: I joined the BU Department of Computer Science in 1999 after completing my Ph.D. at UC Berkeley. My research interests are broadly focused on algorithmic and economic aspects of e-commerce, networking, and large-scale data management, striking a balance between theoretical foundations and rigorous data-driven experimentation.

Entrepreneurial: I am currently Chief Scientist and a member of the Board of Directors at Cogo Labs, a start-up based in Cambridge, MA, where I've had an executive role since the company's founding in 2005. Cogo leverages a unique proprietary technology platform for algorithmic marketing, data mining, and quantitative business analytics to guide portfolio companies from inception to profitability and beyond.
