Profile & Experiences:

Dr. Oyeniyi Stephen Bejide is a seasoned enteric pathogens researcher and clinical microbiologist whose research focuses on the application of modern techniques and molecular tools to understand the epidemiology of infectious pathogens and the molecular mechanisms underlying their transmission and pathogenicity. His work is directed toward developing evidence-based strategies to curb the spread of pathogens that constitute major public health threats.

Dr. Bejide is currently a Lecturer II in the Department of Biological Sciences at Augustine University. His administrative responsibilities include serving as Seminar Coordinator and Adviser to 100-Level students. He also previously served at Chrisland University, where he received commendations for his meritorious contributions to the Department of Microbiology and the University community.

He contributed to Nigeria’s National Action Plan for Antimicrobial Resistance (2017–2022), demonstrating his commitment to strengthening antimicrobial resistance surveillance and public health interventions in Nigeria.
