Classius Ferreira da Silva has a background in Chemical Engineering (State University of Maringá - 1996), Master in Food Engineering (State University of Campinas - 1998), and Ph.D. in Chemical Engineering (University of Campinas -2006). Classius is an Associate Professor at the Federal University of São Paulo, where he teaches Unit Operations, Biopolymers and Materials Science for graduate and undergraduate students. Classius has developed and supervised works with biopolymers in many applications, including food, packaging systems, wound dressing, and drug delivery systems.

Rodrigo Silveira Vieira is Associate Professor in the Chemical Engineering Department at the Federal University of Ceará (Fortaleza, Brazil) and Invited Professor at the Mines, Materials and Metallurgic Engineering Department, at Laval University (Québec, Canada). Prof. Vieira has explored renewable sources of raw materials, especially natural polymers, to propose materials with aggregated values, that can be used for health, environmental and energy applications. This includes the development of sulfated polysaccharides for use as devices in contact with blood that can be used for coating metal surfaces (stents), hybrid materials (bacterial cellulose/hydroxyapatite) functionalized with metal ions (Sr) for osseous integration applications, antimicrobial polysaccharides properties against planktonic and biofilm formation (fungi and bacteria), and glycerol valorization (environment and energy).
