Paper accepted to COLT 2016!
New pre-print on online learning with abstentions now on arxiv.
I am organizing the AI Seminar this quarter.
New pre-print on privacy-preserving statistics on correlated data now on arxiv.
Upcoming talk at AISTATS (May 2016).
I am an Area Chair for ICML 2016, UAI 2016 and NIPS 2016, and a PC member for COLT 2016.
Three papers accepted to NIPS 2015!
I have been elected a Steering Committee Member for COLT.
My research is on machine learning. Much of my work is on privacy-preserving machine learning and unsupervised learning, but I am broadly interested in a number of topics in learning theory, such as confidence-rated prediction, online learning, and active learning.
Here is a survey I wrote on machine learning with privacy. Here is an overview I wrote in 2008 about learning mixture models. Here is a press article on Biomedical Computation Review that talks about some of my work on privacy-preserving machine learning.
