Prof. Maria Isabel Rodrigues (University of Campinas, Brazil)
Professor Maria Isabel Rodrigues received her BS, MS, and PhD degrees in food engineering from the Faculty of Food Engineering (FFE), University of Campinas, Brazil. She started as a lecturer in FFE in 1989 and became a full professor in 2001. Professor Rodrigues has been using design of experiment methodology since 1990 and has taught courses of experimental design and process optimization at postgraduate level in FFE, in private companies, and at other universities and institutions.
She has worked as a consultant using this statistical tool in various specialty areas such as bioremediation, developments in microbial analytical methods, and fermentation and enzyme processes as well as in the automotive, chemical, petrochemical, cosmetic, pharmaceutical, and food industries.
The aim of this workshop is to introduce the experimental design technology and response surface methodology to academics and R&D professionals. The “trial and error” method has been considered outdated: despite the waste of time and material, it is not always possible to evaluate the effects that the variables have on expected responses and/or reach the optimized conditions with reliability of obtained responses. The statistical design tools, if well applied, provide higher reliability for interpretation and discussion of results. They have been considered effective and essential, either for process and product development or for improvement of the existent ones. In this context, several strategies may be used: Fractional Factorial or Plackett Burman designs are excellent for preliminary evaluation of the variables and selection of those to be considered by the Central Composite Rotatable Design (CCRD), if necessary. In this workshop, it will be approached appropriate strategies to be chosen as a function of involved factors as well as the risks of using these methodologies without the knowledge of their fundaments (by real case studies).
