Dr József BaranyiDr 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 Group
  • Author or co-author of some 50 refereed research papers and edited chapters, with a total citation > 2500. The Baranyi model on bacterial growth is one of the most frequently quoted models in predictive food 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 1996 - 2010
  • Member of the Editorial Board of Applied and Environmental Microbiology since 1998
  • Editor, BMC Microbial Informatics and Experimentation, since 2010

Main interests:

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