Dr József Baranyi

Research Leader

• Mathematician, working on modelling microbial responses to food environments. Joined the Institute of Food Research in 1990.
• Leader of the Computational Microbiology Research Team
• Author or co-author of some 50 refereed research papers and edited chapters, with a total citation index of ca 2000. The Baranyi model on bacterial growth is one of the most frequently quoted models in predictive microbiology.
• Invited speaker and scientific committee member in numerous international conferences.
• Has been coordinating and participating in several projects funded by UK government, EU and industry. Invited expert on UK and EC projects and panels.
• Statistical advisor of Journal of Applied Microbiology since 1996
• Member of the Editorial Board of Applied and Environmental Microbiology since 1998
• Member of Institute of Mathematics and its Applications, UK (Chartered Mathematician, Chartered Scientist)

Main interests:

• Dynamic modelling of bacterial growth, survival and death.
• Modelling microbial complexity.
• Databases on microbial responses to the food environment - see ComBase
