Short Bio: My
research interests lie in privacy in statistical databases, privacy in
augmented reality systems, and systems for massive data analytics. Previously, I was a Senior Research
Scientist at Yahoo! Research. My thesis was awarded the 2009 SIGMOD Jim Gray Dissertation Award, Honorable Mention.

Prospective Students: I am primarily interested statistical privacy,
or the problem of disclosing aggregate statistics about data collected
from individuals, while ensuring that individuals level sensitive
properties are not disclosed. This problem appears in a number of
diverse application settings including in the US Census, social networks,
search logs, location
tracking, etc. Read one of the following articles to get an idea of my research: (ACM Crossroads article, no free lunch in privacy, CACM article, Blowfish privacy).
I am also interested in privacy of visual secrets in augmented reality
systems -- an evergrowing threat due to the popularity of camera driven
devices like smart phones and Google Glasses. Read this paper for an overview of our research.
