Dr. Yong received his Ph.D in computer science from The Hong Kong University of Science and Technology in July 2002, and then worked as a postdoctoral researcher at DIMACS (NSF center at Rutgers, The State University of New Jersey) until August 2004. During the 2004-05 academic year he served as a lecturer for the Department of Computer Science and the Department of Mathematics at Rutgers and then, in August 2005, joined the Department of Mathematical Sciences, University of Puerto Rico at Mayaguez. He has also been a visiting researcher at DIMACS. Earlier in 1991 he earned doctorate in mathematics from Xi'an Jiaotong University.
