Wei Zhang

  • Professor, Food Science and Nutrition
  • Assoc. Director

Education

Ph.D., Pennsylvania State University
M.S., Huazhong Agricultural University
B.S., Huazhong Agricultural University

Research Interests

Dr. Zhang’s research interests include molecular detection, genotyping, stress response, virulence and pathogenesis of foodborne bacteria. The long-term goal of his research is to better understand the genetic and physiological basis by which bacterial pathogens colonize various environmental niches, survive and grow in foods, transmit to human and cause infectious disease, using cutting-edge bioinformatics and high-throughput genomic approaches.
