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.
