Professor | National Research Centre | Egypt
Dr. Sherif Ramzy Mohamed is a Professor of Food Toxicology and Contaminants at the National Research Centre (NRC), Egypt, where he has served since 2018 following earlier roles as Assistant Professor (2013) and researcher. He holds a Ph.D. in Food Science and Technology (2008), preceded by an M.Sc. (2002) and B.Sc. (1997) in the same specialization. His research centers on food toxicology, mycotoxins, food contaminants, rapid detection techniques, biodegradation mechanisms, and non-traditional strategies for food safety risk mitigation. Emerging interests include smartphone-integrated diagnostic systems, microbial enzymatic degradation of toxins, fungal genomics, and sustainable biocontrol technologies. Over his career at NRC and through joint Egyptian-Chinese scientific collaborations, he has led major projects on the early warning, monitoring, and prevention of mycotoxins in grain supply chains, securing international research partnerships and grants. Among his key contributions are the development of manganese dioxide nanoribbon-based sensors for aflatoxin B1 detection, smartphone-controlled infrared spectrometry for fumonisin identification, genome-based interventions to reduce toxin biosynthesis, and innovative biological mechanisms for toxin degradation. He has also co-developed methods for eliminating fungal contaminants via autophagy control and pioneered research on bacterial strains capable of degrading zearalenone and other estrogenic toxins. His work has resulted in multiple patents, including a 2023 international patent on enzymatic biodegradation of zearalenone and earlier patents on rice straw applications and antiviral botanical extracts. He has published more than 60 peer-reviewed papers in Q1 and Scopus-indexed journals and vetted more than 150 manuscripts. His roles extend to editorial boards of international journals such as Annals of Food and Nutrition Research, Nutrition and Food Toxicology, Universal Journal of Food Science and Technology, and Journal of Food Technology and Food Chemistry. He is a fellow of the Board of Quality Standards (BU-FBQS) and an active member of professional bodies including the Egyptian Society of Natural Toxins, Asia Society of Researchers, and the International Society of Substance Use Professionals. His honors include multiple research productivity awards from the NRC and the Khayria Naguib Prize (2015). Through his scientific advisory work, conference participation, and supervision of postgraduate theses, he has shaped food safety research in Egypt and internationally. His long-term vision is to reduce the economic and health burden of foodborne contaminants by developing rapid, affordable detection tools, eco-safe biodegradation technologies, and evidence-based policies that enhance global food security, public health protection, and industrial innovation. He has 1007 citations from 33 publications, with an h-index of 15.
