    I am an anaerobic microbiologist ,with special interest in the microbial functions in the  gastrointestinal tracts of human and animals , particularly their roles in cancer formation.  I am a member of American Society for microbiology, Institute of food Technologists, Environmental Mutagenesis and Genomics Society.  I constantlyreview papers for Environmental and Molecular Mutagenesis, Food and Chemical Toxicology,Mutation Research, Toxicological In Vitro, etc.   Since 2009 I have been the managing editor for the special issue of Arylamine Induced Carcinogenesis of Fronitiers in Biosciences.

    Currently I am teaching Introduction to Microbiology (Biol 1230), Public Health Microbiology (Biol 7080/8080) and Food and Industrial Toxicology (Biol 7555/8550).



I came to the University of Memphis in 1988. I have a B.S. degree (1965) from National Taiwan University (Taipei) major in Agricultural Chemistry; M. A. degree (1967) major in Biology from University of California, Santa Cruz;  and Ph. D. (1972) major in microbiology from University of California.  Previously, I served as a visiting scientist at the USDA Roman, ARD USDA, ARS, Roman L. Hruska U.S. Meat Animal Research Center, Clay Center, Nebraska; Associate Professor in Tunghai
University (Taichung, Taiwan); Professor in Soochow University (Taipei); Scientist in Frederic Cancer Research Facility in Frederick, Maryland.
