Xiaojun Chang 

Greetings! I received my Ph.D degree at Centre for Quantum Computation and Intelligent Systems (QCIS), University of Technology Sydney. My supervisors was Dr. Yi Yang. I was also co-supervised by Dr. Feiping Nie. Now I have been working as a postdoctoral research associate in the Language Technologies Institute at Carnegie Mellon University, working with Dr. Alexander G. Hauptmann.

My research interest is mainly on machine learning and its applications to multimedia analysis and computer vision.
