Biography Summary

Alexander Penlidis is a Chemical Engineering Professor at the University of Waterloo, as well as a Tier 1 Canada Research Chair in Engineering of Polymers with Tailor-Made Properties. He is the founding co-editor and editor for the "Polymer Reaction Engineering Journal" and also served as the Associate Director and Director for the Institute for Polymer Research from 1991 to 2010.

His long-term goal is to promote in parallel interdisciplinary research for polymers with advanced technology applications. These applications would be geared towards health, biological polymers, polymeric sensors, polymeric materials for photonics, and polymeric materials for a variety of civil engineering applications.

Professor Penlidis’s current projects include kinetics and modelling of multicomponent bulk, solution, suspension and emulsion polymerizations; development of flexible simulator packages for polymerization processes; and dynamic optimization of polymer reactor operation, polymer reactor pilot-plant instrumentation and automation. He is also working on online multivariable non-linear model predictive control of polymerization reactors; high temperature terpolymerizations and depropagation studies, as well as nano-structured particle technology.

Professor Penlidis has made outstanding research accomplishments, culminating in the 1993 Canadian Society of Chemical Engineering Albright and Wilson Americas Award, for distinguished contributions in chemical engineering before the age of 40. Additionally in 2002, he was elected a Fellow of the Canadian Academy of Engineering (FCAE), the highest engineering honour in the country. In light of his impressive work, Professor Penlidis has attracted more than $15,500,000 in research funding.
