Research

Research interest:

Machine Learning (learning from noisy and incomplete data), optimization (robust optimization and convex optimization for large data), data analysis, network analysis, bioinformatics (micro-array data analysis and molecular network analysis) .

Summary:

I am currently working on various application of machine learning in network. I am also interested in modeling Kernel method for learning with multi view, noisy or incomplete data.
