Dr. Wang received her Ph.D. degree from University of Minnesota in 1998 and post-doctoral training from NIH in 1999. She served as a consumer food safety officer for FDA in 2000, and currently is a tenured associate professor in Department of Food Science and Technology, Microbiology, Interdisciplinary Ph.D. Program in Human Nutrition (OSUN), and the Center for Microbial Interface Biology (CMIB) at the Ohio State University.

Dr. Wang’s main research interests are 1) rapid detection of microorganisms and hazardous genes in foods; 2) microbial biofilms; 3) antibiotic resistance in food and human microbial ecosysytems; and 4) food and foodborne microbes in shaping the host digestive microbial ecosystems. Her research group discovered a large pool of antibiotic resistant commensal (including non-pathogenic and beneficial) bacteria with mobile resistance genes transmissible to human residential bacteria and pathogens in commonly consumed food items, and revealed the potential role of commensal bacteria as facilitators in horizontal gene transmission. These studies, along with data from other laboratories, suggested that the food chain might have played an important role in the dissemination of antibiotic resistance to humans and shaping the development of host digestive microbial ecosystems (Appl. Environ. Microbiol. 2005. 71:2970-2978; FEMS Microbiol Lett. 2006. 254: 226-231; Appl Environ Microbiol. 2007. 73:1676-1677; Her group also defined the first “honeycomb” biofilm structure using Listeria monocytogenes as the model organism (FEMS Microbiol Lett. 2003. 228:203-210), and demonstrated the role of conjugation in microbial biofilm ecosystem development in Gram-positive bacteria using the Lactococcus lactis model system (Appl. Environ. Microbiol. 2005. 71:2970-2978). Dr. Wang has a long term interest in genetics of lactic acid bacteria, and she is actively involved in microbial community-based studies in the food science arena by having more than 80 peer-reviewed journal articles, book chapters, professional conference presentations and various invited talks, by organizing symposia for Institute of Food Technologists (IFT) and American Society for Microbiology (ASM), and by coordinating and editing books for professional publishers such as ASM Press and Blackwell Professional Publication, Inc. on related subjects. She was a member of the NASA External Advisory Board, Specialized Center of Research and Training for Advanced Life Support (Trip to Mars), editorial board for Journal of Food Protection, and served as panel members and Ad Hoc reviewers for USDA and other funding agencies and professional journals. She currently serves as Chair-elect of IFT Biotechnology Division, and is selected as the lecturer for the 2008-2010 American Society for Microbiology Branch Lectureships (ASMBL, formerly Waksman Foundation for Microbiology Lectures) program (
