I am a Researcher at Technicolor Palo Alto,
a research lab focusing on recommender systems and user data privacy.
Prior to joining Technicolor, I was a postdoctoral fellow at the
Computer Science Department,
University of British Columbia,
working with
Laks V. S. Lakshmanan.
I completed my PhD research under the supervision of
S. Muthukrishnan
at the Department of Computer Science,
Rutgers University.
My research interests are rooted in social networks,
and my work explores various aspects of mining, modeling
and analyzing these networks.
I am working on problems in recommender systems that go
beyond user/item recommendations, for instance, privacy in recommender systems, and
recommending sets of items.
My recent work studies influence in social networks to maximize
product adoption in the context of viral marketing.
During my PhD, I worked on the complementary problems of
inference and privacy in social network data management.

A few smiles :)
A non-negative linear combination of these terms can approximately
