Research Interests:

Statistical Relational Learning, Semi-supervised learning on networked data (aka. within-network learning), Machine Learning, Information Integration/Aggregation/Filtering/Ranking, Text Classification.

About me:

Haym Hirsh was my advisor in my thesis work on Intelligent Information Filtering. I was a member of the Rutgers Machine Learning Research Group, while at Rutgers.

I went to NYU Stern School of Business as a Research Scientist after I graduated, working with Foster Provost.

I am now at Fetch Technologies.
