Christopher C. Yang is an associate professor in the College of Computing and Informatics and holds a courtesy appointment in the School of Biomedical Engineering, Science, and Health Systems at Drexel University. His recent research interests include healthcare informatics, security informatics, social intelligence and technology, Web search and mining, knowledge management, and information visualization. He has published over 250 referred journal and conference papers in ACM Transactions on Intelligent Systems and Technology, ACM Transactions on Management Information Systems, Journal of the American Society for Information Science and Technology (JASIST), IEEE Transactions on Knowledge and Date Engineering, IEEE Transactions on Systems, Man, and Cybernetics, IEEE Transactions on Image Processing, IEEE Transactions on Robotics and Automation, IEEE Computer, IEEE Intelligent Systems, Decision Support Systems (DSS), Information Processing and Management (IPM), Graphical Models and Image Processing, Optical Engineering, Pattern Recognition, International Journal of Electronic Commerce, and more.
He is currently serving as the editor-in-chief of Journal of Healthcare Informatics Research (Springer) and the co-editor of Electronic Commerce Research and Applications (Elsevier). He was the associate editor-in-chief of Security Informatics (Springer) . He has edited several special issues on social media, healthcare informatics, security informatics, Web mining, multilingual information systems, knowledge management, and electronic commerce in IEEE Transactions, ACM Transactions, IEEE Intelligent Systems, JASIST, DSS, IPM, and others. He is the steering committee chair of IEEE International Conference on Healthcare Informatics and has chaired in many international conferences and workshops such as ACM SIGHIT International Health Informatics Symposium, IEEE International Conference on Intelligence and Security Informatics, ACM International Conference on Information and Knowledge Management, International Conference on Electronic Commerce, International Conference on Social Intelligence and Technology, ACM SIGKDD Workshop on Intelligence and Security Informatics, ACM SIGKDD Workshop on Health Informatics, International Workshop on Smart Health and Wellbeing, and International Conference on Asia-Pacific Digital Libraries. He is also the editor of the CRC book series on Healthcare Informatics and is frequently serving as an invited panelist in NSF and other government agencies review panels.
In his recent work on healthcare informatics, he is closely collaborating with USC Keck School of Medicine, UCSF School of Medicine, Marshfield Clinic Research Institute, the Children's Hospital of Philadelphia, UPenn Medical School, and Johnson & Johnson. Actonnect, one of his collaboration with Marshfield Clinic Research Institute, University of Wisconsin at Madison, and a couple other institutions, has won the first place of conceptual model in the PCORI Patient-Research Matching Challenge in 2013. Actonnect is a web-based search engine and interface that aims to enable patients, clinicians, researchers, and others to conduct searches of health information gleaned from dozens of patient forums and social media sites and share their results graphically. His work has been supported by National Science Foundation, National Institutes of Health, Pennsylvania Department of Health, Children's Hospital of Philadelphia, Institute of Museum and Library Services, Hong Kong Research Grant Council, Hong Kong Innovation and Technology Fund, and Hong Kong SAR Government. He received his PhD, MSc, and BSc in computer engineering from the University of Arizona.
