Kei-Hoi Cheung, PhD

Professor of Biomedical Informatics & Data Science; Professor, Biostatistics



Kei-Hoi Cheung, PhD has distinguished himself as a researcher and educator in the field of Biomedical Informatics with a growing national and international reputation. A particular strength is Dr. Cheung’s ability to forge strong, productive collaborations with a range of different bioscience researchers at Yale, in which his contributions include the development of complex databases and informatics tools that are critical for the research projects being performed. In the context of these collaborations, Dr. Cheung is simultaneously able to carry out his own informatics research on issues involved in robust interoperation and integration of databases and tools in the biosciences. In addition to giving talks and presentations at national and international meetings, he has published his own informatics research in peer-reviewed journals and conference proceedings, as well as contributing to publications focused on his collaborators’ research. He has established a broad base of collaborations with faculty in different departments at Yale, including Genetics, Pathology, Computer Science, Biostatistics, Molecular Biophysics and Biochemistry, and Biology. He was Director of Biostatistics and Bioinformatics Core of the NIDA Proteomics Center, focused on collaborative informatics support of neuroproteomics research at Yale. In addition to being a collaborator on numerous grants, Dr. Cheung has been PI on several federal grants (NIH and NSF). Dr. Cheung is also a core faculty member of Yale's Ph.D. Program in Computational Biology and Bioinformatics.

Dr. Cheung’ s research interests include the semantic web using the next generation of web technologies to integrate life science data and tools, and is co-editor of two books for Springer-Verlag titled: “Semantic Web: Revolutionizing Knowledge Discovery in the Life Sciences” and “Semantic e-Science”, respectively. Dr. Cheung also led the BioRDF task force (2008-2010) of the Semantic Web for Health Care and Life Sciences Interest Group that is an international community engaging in the creative use of Semantic Web in biomedicine. In addition, Dr. Cheung has recently embarked on natural language processing (NLP) projects in annotating, extracting and retrieving information from clinical text as part of the Veteran Administration (VA) electronic medical records. In summary, Dr. Cheung’s biomedical informatics expertise in database/semantic web research and NLP tool development, his national and international recognition as a researcher/educator, and his research contributions in these areas exemplify the attributes of a prominent researcher in biomedical informatics.

Education & Training

  • PhD
    University of Connecticut, Computer Science (1998)


  • SenseLab Project
    Austria; China; South Korea 2006
    This is a neuroscience informatics project involving the exploration of Semantic Web technologies in neuroscience data integration. In 2006 a visiting scholar from Zhejiang University, Hangzhou, Zhejiang, China came to YCMI to collaborate with Dr. Cheung on this neuroinformatics project. A PhD student from University of Vienna, Austria visited YCMI to work with Prof. Cheung as a summer intern on the SenseLab/Semantic Web project. It appears likely that a professor from the Catholic University of
  • Bioinformatics Summer Exchange Program
    Hong Kong (2005-2006)
    This is a summer program that has been established between the University of Hong Kong's (HKU) Bioinformatics Program (which is an undergraduate program) and Yale Center for Medical Informatics (YCMI) which is affiliated with Yale's Computational and Bioinformatics (CBB) PhD program. Prof. Cheung is the director of this exchange program. In the summers of 2005 and 2006, a visiting undergraduate student sponsored by HKU's Bioinformatics Program was sent to Yale's STARS Summer Program to take a su
