John Leong is the Edith Rieva and Hyman S. Trilling Professor and Chair of Molecular Biology and Microbiology at Tufts University School of Medicine. His research program focuses on bacterial pathogenesis and host-microbe interactions, with emphasis on three primary pathogens: Enterohemorrhagic Escherichia coli (EHEC), Streptococcus pneumoniae, and Borrelia burgdorferi (Lyme disease spirochete).
Education:
- Bachelor of Arts, Brown University (1979)
- Doctor of Philosophy, Brown University (1985)
- Doctor of Medicine, Brown University (1987)
Research Focus: Dr. Leong investigates mechanisms of bacterial colonization, damage induction, and immune evasion during infection. His work spans from basic molecular mechanisms to translational applications including:
- Development of murine EHEC infection models
- Modulation of host immune responses to pneumococcal infection
- Spirochete-host interactions enabling bloodstream survival
- Engineered probiotics and nanobody therapeutics
Publications: Dr. Leong has published over 200 scholarly articles primarily focused on bacterial pathogenesis, immune evasion mechanisms, and therapeutic innovations. Recent work demonstrates strong emphasis on:
- Epithelial barrier disruption mechanisms during infection
- Complement system evasion strategies by pathogens
- Development of engineered microbial therapeutics
- Genomic determinants of pathogen dissemination
Awards and Honors:
- Edith Rieva and Hyman S. Trilling Endowed Professorship
- Elected Fellow, American Academy of Microbiology
- Tufts Discovery Award
Grants and Funding: Extensive support from NIH, Bill & Melinda Gates Foundation, and private foundations for projects including:
- Microbial determinants of Lyme disease heterogeneity
- Designer probiotics for intestinal infections
- Functional analysis of bacterial adhesins
- Safe iron delivery systems
Teaching: Regularly teaches courses including Introduction to Microbiology, Microbiology/Infectious Disease & Immune System, and Immune Mechanisms in Disease at both graduate and medical student levels.
