Research interests: machine learning, data mining, information retrieval, and

computer vision. My PhD thesis is dedicated to large-scale machine learning algorithms 

for classification and search. Currently, I am working on combinatorial, parallel, and distributed optimization methods to tackle noise/outlier present, high-dimensional, and large-scale learning problems. I am particularly interested in developing binary coding

and hashing techniques to handle big data.
