Liliane Lona has degree (1991), master’s (1994) and PhD (1996) in Chemical Engineering from the University of Campinas (Unicamp). She developed postdoctoral studies at the Institute for Polymer Research at the University of Waterloo - Canada (2002). Her master’s and PhD were related to modelling and simulation of petrochemical processes and her post-doctoral studies in the area of modelling, simulation and optimization of polymerization reactors. In 1996 Liliane became professor at School of Chemical Engineering - Unicamp and in 2010 she became full professor in the area of analysis and simulation of chemical process. Liliane Lona taught for more than 20 times an undergraduate course related to the area of this book. She supervised dozens of grade and undergraduate students in the modeling and simulation area, and many of this works received awards, such as i) BRASKEM/ Brazilian Association of Chemical Engineering Award (2007), ii) Petrobras Award Pipeline Technology (2000 and 2003), iii) Regional Council of Chemistry Award (2000). Liliane published many scientific papers in qualified journals and was postgraduate coordinator (2006-2010) and Director (2010-2014) of the Chemical Engineering School - Unicamp.
