Profile/About Me
Dr. Tzeng received his undergraduate training at the Department of Food Science, Tunghai University, Taiwan. He completed his graduate training and earned a PhD in Microbiology at the Department of Microbiology and Molecular Medicine, Clemson University, USA. Dr. Tzeng has taught microbiology courses at all levels. His research interests focus on the development of non-antibiotic approaches for the prevention and treatment of microbial infections. The long-term goal of his research is to develop prevention and therapeutic approaches to reduce, augment, enhance, or replace the use of antibiotics. The approach he takes to achieve the goal is to study the microbe and host interactions as well as the mechanisms enabling the microorganisms to be resistant to the actions of antibiotics. Understanding of these interactions and resistance mechanisms will enable us to develop effective disease prevention and treatment methods. He has published 70+ manuscripts and received funding from USDA, NSF, NIH, Army, and private sectors and collaborated with physicians in Prisma Health.
Research Interests
The long-term goal of my research is to develop prevention and therapeutic approaches to reduce, augment, enhance, or replace the use of antibiotics. My approach to achieving this goal is to study the microbe and host interactions as well as the mechanisms enabling the microorganisms to be resistant to the actions of antibiotics. Understanding of these interactions and resistance mechanisms will enable us to develop effective disease prevention and treatment methods.
Under this vision, my team has 1) developed nanoparticles that display multivalent bacterial adhesin-specific receptors mimicking host cell surface, to facilitate their bindings to targeted bacteria; 2) functionalized iron-oxide nanoparticles with adhesin-specific receptors to study the feasibility of using such magnetic nanoparticles for inactivation of targeted microorganisms; 3) developed biosensors for rapid and sensitive detection of targeted pathogens; 4) developed modified surfaces, e.g., surgical pins and plates, that minimize bacterial infections and/or prevent bacterial attachment (biofilm formation); 5) developed antimicrobial peptides that are target-specific to control the growth of foodborne pathogens and to minimize the emergence of antibiotic resistant bacteria; 6) identified nutraceutical compounds that exhibit antimicrobial activities but with low host toxicities; 7) purified bacterial efflux pump inhibitors from nutraceuticals to facilitate the effective treatment of multi-drug-resistant pathogens; 8) developing poultry feed formulations for organic and antibiotic-free production of layers and broilers.
