• Dr. Tan is an Associate Professor of Computer Science. He received the M.A and Ph.D. degrees from Princeton University. He was a Senior Fellow of the Institute for Pure and Applied Mathematics (IPAM) for the program on Science at Extreme Scales, and was a Postdoctoral Scholar in the NetLab Group at Caltech. His industrial experience includes consulting for Tencent AI Lab, Qualcomm R&D (QRC), Fraser Research Lab. His research interests are artificial intelligence, cognitive cloud computing, networks and graph analytics in scientific machine learning, convex optimization theory and its software, and online learning. He is also interested in computer science and mathematics education and gifted education. His Erdös number is 3.
  
  Three different three-hop paths:
  C. W. Tan → A. R. Calderbank → J. H. Spencer → Paul Erdös
  C. W. Tan → S. Friedland → H. Minc → Paul Erdös
  C. W. Tan → H.-L. Fu → C. J. Colbourn → Paul Erdös

  The Erdös number is an example of a social network, and Dr. Tan's current research on network science explores the mathematics and algorithms of web analytics and artificial intelligence.
  
  Dr. Tan has served in TPC of ACM SIGMETRICS, International Joint Conference on Artificial Intelligence (IJCAI) and as Editor for the IEEE/ACM Transactions on Networking and IEEE Communications Surveys and Tutorials. He received the Princeton University Wu Prize for Excellence, Google Faculty Award, university teaching awards, and was selected twice for the U.S. National Academy of Engineering China-America Frontiers of Engineering Symposium. His research was featured in Hong Kong Research Grants Council's Research Frontiers. He has previously served as the Editor of the IEEE Transactions on Communications and as the IEEE Information Theory Society Hong Kong Chapter Chairman receiving the 2015 IT Society Chapter of the Year award. He organizes the Computer Science Challenge, NASA Space Apps Challenge (HK) hackathon and the Education Bureau's Programme on Creative Mathematics and Computer Science Learning for Gifted Students.
