Biography

George Vamvounis is the Head of Chemical Engineering (acting) at James Cook University. George obtained his PhD from Simon Fraser University where he developed Polymer and Organic Light Emitting Diodes. Following his PhD, George worked at the Royal Institute of Technology (KTH) in Stockholm, Sweden and The University of Queensland’s Centre for Organic Photonics and Electronics (COPE) where he investigated dendrimers and dendronised polymers. In 2014, George moved to James Cook University where he is an Associate Professor of Chemical Engineering. His research interests are in polymer semiconductors and understanding ecological risks of plastic pollution.

Research

Research Interests

I am a Polymer Chemist, and my research is translational in nature, focusing on advancing our understanding of sustainability. To that end, my research relates to (1) polymer semiconductors and (2) understanding and solving plastic pollution.

(1) Polymer semiconductors are revolutionizing how we generate and use energy (e.g., Polymer Solar Cells and light-emitting diodes). My research is focused on the preparation, characterization, and modeling of polymer semiconductors for these applications.

(2) Plastic pollution, particularly in the form of microplastics, is growing rapidly, and we need to understand its ecological effects and propose solutions. My research focuses on additive leaching processes and the development of sustainable alternatives.

Teaching

Teaching Interests

Teaching Philosophy: I believe that a student’s ability to grow in his/her understanding of the topic is facilitated by (a) bridging their existing knowledge with their new learning experience, (b) promoting healthy communication and (c) promoting interest in the curriculum. When used together, I believe that student learning can be maximized to enable long-term retention with diverse student backgrounds and experiences.
