I am a postdoctoral fellow in
Machine Learning Department
at Carnegie Mellon University.
My general research interest lies in statistical machine learning techniques for problems in computational biology. I am developing structured regression models for disease association and biological network analysis. I am also interested in non-parametric Bayesian models for biological data analysis.
In December 2011, I received my Ph.D in
Computer Science Department at CMU under the advising of
Eric P. Xing.
