Joao B. P. Soares is a Professor in the Department of Chemical Engineering at the University of Waterloo. Before moving to Canada, he worked during four years as an R&D engineer for Pronor, COPENE, and Polibrasil (Brazil). He did his PhD thesis under the supervision of Professor A.E. Hamielec, in the Department of Chemical Engineering at McMaster University and joined the faculty in the Department of Chemical Engineering at the University of Waterloo in 1995.Professor Soares' research interests are: polymerization reactor engineering for Ziegler-Natta, metallocene, late transition metal, free-radical and living free-radical polymerization, polymer microstructural characterization and fractionation, mathematical modeling of polymer microstructure, and in-situ polymer nanocomposites.Professor Soares is recipient of the Premier?s Research Excellence Award (2000), the Union Carbide/Dow Innovation Recognition Program (2000,2001), and the Syncrude/CSChE Canada Innovation Award (2001).
