The Stoppel Lab focuses on topics related to:

• Biomaterial design and development using natural biopolymers
• Development of bioactive molecule delivery systems as solutions to current healthcare challenges, including injectable and implantable materials
• Investigation and leveraging of biodiversity to identify and harness the potential utility of non-commercialized biopolymers from insects for applications in healthcare and medicine
• Quantification and optimization of transport and kinetics within 3D biomaterial systems for predicting and controlling in vivo performance
• Muscle regeneration and methods for generating engineered tissues
• Designing materials to alter wound healing and disease progression
