Breve currículo do Prof. Baranyi:

Prof József Baranyi, a mathematician, was the head of the Computational Microbiology Research Group at the Institute of Food Research, Norwich, UK.  He is a Fellow of the of International Academy of Food Science and Technology, and a recipient of the Distinguished Service Award of the American Society for Microbiology.  Author or co-author of ca 80 refereed research papers, with >4000 citations; invited speaker, scientific committee member in numerous international conferences; has coordinated several projects funded by UK government, EU and industry. Co-founder of the ComBase Consortium, 2003 (www.combase.cc).  Held > 100 workshops all around the world on ComBase and the use of mathematical models and biostatistics in microbiology. He was the statistical advisor of Journal of Applied Microbiology for 15 years and a member of the Editorial Board of Applied and Environmental Microbiology for 16 years. Currently he is member of the Editorial Board of the International Journal of Food Microbiology. His mathematical model on bacterial growth, named after him, is one of the most frequently quoted models in predictive microbiology.
