Dr. Zhang is McKnight Presidential Fellow and Associated Professor at the University of Minnesota. He has joint appointments in the Department of Pharmaceutical Care & Health System (PCHS) and the Institute for Health Informatics (IHI). He leads the Clinical Informatics PhD track in Health Informatics graduate program, and also faculty in the graduate program of Data Science, Bioinformatics and Computational Biology (BICB). He is the Director of Natural Language Processing (NLP) services in BPIC of CTSI.  Dr. Zhang’s research focuses on biomedical informatics, especially artificial intelligence (AI), biomedical and clinical NLP, knowledge representation and pharmacy informatics. Dr. Zhang’s research focuses on the development of novel AI methods to analyze biomedical big data, including biomedical literature, electronic health records (EHRs), patient-generated data and knowledge bases. His research include but not limited to: i) the secondly analysis of EHR data for patient care, ii) pharmacovigilance knowledge discovery through mining biomedical literature and iii) creation of knowledge base through database integration, terminology and ontology. 

 His research program is funded by federal agencies such as National Institutes of Health and Agency for Health and Research Quality, as well as industries such as Medtronic Inc. His work has been recognized on a national scale including Journal of Biomedical Informatics Editor’s Choice, nominated for Distinguished paper in AMIA Annual Symposium andMarco Ramoni Distinguished Paper Award for Translational Bioinformatics, as well as highlighted by The Wall Street Journal. Dr. Zhang has served on several NIH study sections, the Editorial Board for Journal of American Medical Informatics Association (JAMIA), Chair of AMIA Student working group, and co-chaired international workshops, such as HealthNLP and Semantics-powered Health data analytics (SEPDA). Recently, Dr. Zhang was inducted into the Fellow of AMIA (FAMIA).

“Researchers at the University of Minnesota in Minneapolis are exploring interactions between cancer drugs and dietary supplements, based on data extracted from 23 million scientific publications, according to lead author Rui Zhang, a clinical assistant professor in health informatics. In a study published last year by a conference of the American Medical Informatics Association, he says, they identified some that were previously unknown.”
