Dr. GQ Zhang, Division Chief for Medical Informatics, is Co-Director of Informatics for the Cleveland Clinical and Translational Science Collaborative - CTSC (CTSA; UL1-RR024989), Associate Director for Cancer Informatics in Case Comprehensive Cancer Center (CA043703), and Professor of Electrical Engineering and Computer Science, the Center for Clinical Investigation (secondary), and the CPB (secondary).

Dr. Zhang received his B.S. in Applied Mathematics from Nanking Aeronautical Inst. of Technology, an MS. in Information Sciences from Peking University and a Ph.D. in Computer Science from Cambridge University. He held academic appointments at the University of Georgia, University of Michigan prior to joining the faculty in Electrical Engineering and Computer Science at CWRU Case School of Engineering in 2000 as an Associate Professor. Dr. Zhang was promoted to the rank of Professor in 2008.

Professor Zhang received Glennan Fellowship from the Case Center for Instruction and Teaching Excellence, Best Poster Award (ImTK Consortium) Distinguished Paper Award (AMIA Annual Symposium), and Best Paper Award Finalist (International Semantic Web Conference).

Research Interests

Dr. Zhang's research interests include Health Informatics, Clinical Research Informatics, Ontology-driven Web Engineering, and Theoretical Computer Science. He is particularly interested in collaborating with clinical and biomedical researchers to develop informatics tools and infrastructure for clinical translational, comparative effectiveness research.

Dr. Zhang's has been the PI of the NCRR-funded Physio-MIMI project (Multi-Modality, Multi-Resource Environment for Physiological and Clinical Research; NCRR-94681DBS78) and NIBIB-funded project "Phenotyping of Mice using Bioimaging" (K25EB004467), and and serves in the executive and steering committees of several large NIH-funded centers.
