My research interests lie in plastics and carbon dioxide chemistry. This involves discovering how to make plastics from unconventional raw materials, like waste agriculatural co-products or waste gases, and determining the properties of these new sustainable plastics. We investigate how to design plastics for easier recycling and for ultimate biodegradation. Our research focusses on polyesters and polycarbonates. Recent highlights include:
1) Discovery low-pressure catalysts able to transform waste carbon dioxide into useful insulation foams and elastics
2) The preparation of new biodegradable and recyclable plastics for use in packaging and durable goods applications.
Research in my group involves chemistry and materials science and so any applicants should have a strong background in these sciences. My group makes polymers, i.e. synthetic chemistry, but we are also involved in measuring their properties and qualifying environmental impacts. Thus students with interests in materials characterization and environmental impact assessment (practical and theoretical) may also consider applying for supervision.
