I have more than 20 years of professional experience in technology research and development. Areas of focus include computer systems and networks, mobile computing systems and applications, location data analysis and modeling, infrastructure virtualization, security, and privacy.
I'm currently a Software Engineer at Google. I was previously a Lead Member of Technical Staff at AT&T Labs, Research Staff Member at IBM Research, and Chief Scientist of Vindigo, an award-winning provider of location-based services for mobile devices. I hold a Ph.D. in Computer Science from the University of California at Berkeley. I'm an IEEE Fellow and an ACM Distinguished Scientist.
My curriculum vitae contains a more complete career history.
In the last several years my work has focused on characterizing and modeling human mobility. Understanding how people move yields insights into important societal issues, such as the environmental impact of human travel, traffic congestion, and the spread of disease. Cellular telephone networks can shed light on human movements cheaply and on a large scale.
I have initiated and led efforts to analyze billions of location samples for hundreds of thousands of anonymous cellphones to characterize how people move in metropolitan areas such as New York, Los Angeles, and San Francisco. Our results have included range of travel, important places, commuting carbon footprints, commuting routes, and catchment areas. We have also developed differentially private modeling techniques that generate realistic sequences of locations and times for arbitrary numbers of synthetic people moving across metropolitan-scale regions.
My curriculum vitae outlines other previous work.
