  • Mengfei Peng

    Mengfei Peng

    When people experience foodborne illness and diseases, it is not uncommon for their daily lives to suffer. My great passion is preventing consumers from going through such stressful experience. I explore natural methods in control of foodborne bacterial pathogens and help secure table food as both nutritious and safe by doing research in the University.

    It is for sure that no single approach is the perfect one for every illness case, the long-term interest of mine is to apply modern techniques of microbiology, molecular and cellular biology to prevent/treat the bacterial diseases in human through modulation of natural gut microflora with combine effect of probiotics and prebiotics.

    My educational background so far includes a B.A. in biomedical engineering and biotechnology from Beijing University of Technology and a one-year exchanging program in Biological Sciences from the State University of New York – Buffalo. I am currently in my 5th year of Ph.D. in Molecular and Cellular Biology program from University of Maryland.
