Gillies Research Group

Our Expertise

The Gillies group is developing new degradable polymers for environmental benefits and for biomedical applications.

Projects in our lab involve organic and polymer synthesis, characterization, and applications in a wide range of areas. We are active collaborators, working with industry and many academic groups around the world.

Self-immolative polymers

We are using organic and polymer chemistry approaches to design and synthesize new polymer backbones that depolymerize in response to specific stimuli. These polymers offer an unprecedented level of control over the degradation process, and an amplified response to stimuli. They are of interest for wide-ranging applications.

Biodegradable polymers and composites

We are preparing new biodegradable polymers and composites, particularly from bio-based starting materials. We investigate structure-property relationships and applications in different areas.

Polymer functionalization

Our team has expertise in performing pendent group functionalization reactions on polymers to introduce new properties and functions.

Hydrogels

We are using new polymers developed in our lab to prepare hydrogels with new functions and properties for applications such as drug delivery and tissue engineering. Our hydrogels can respond to specific stimuli to degrade, release drugs, and perform other functions.

Intra-articular drug delivery

We are developing new polymeric systems to enable the selective delivery of drugs to articular joints (e.g., knees) and to enable them to penetrate into cartilage to reach specific biological targets.

Compact polyelectrolyte complexes (coPECs)

We are assembling polyelectrolyte complexes from oppositely charged synthetic and bio-polymers and processing them to achieve materials with properties similar to biological tissues. We are examining these materials for applications such as drug delivery and tuning their responsiveness to specific stimuli.

Meet the Team

Our group brings together a diverse team of highly motivated and ambitious researchers.
