Research Interests:

Polymeric biomaterials, degradablepolymers, hyperbranched polymers, photopolymerization, expanding monomers
Polymers used in biomedical materials applications take many different forms and functions. We are designing, synthesizing, characterizing and evaluating novel polymeric materials for a wide array of dental and biomedical applications. Some of these materials, such as dental restorations, are intended for permanent placement while others, as with drug delivery vehicles, can be designed to degrade and clear the body after their service is complete. Other analytical efforts are directed toward a better understanding of existing biomaterials and polymerization processes in general. We are developing new monomers based on free radical polymerization routes that can be used in the body to form completely degradable networks. New pathways to highly versatile hyperbranched polymers are being investigated. These hyperbranched materials are being evaluated as drug delivery devices, controlled microgel particles and macromonomers. Basic photopolymerization studies are underway to better understand the influence that monomer structure and comonomer composition has on polymerization rates and polymer properties in network and interpenetrating network copolymer systems. The unique processing controls afforded by photopolymerization are being exploited to produce novel hybrid polymeric materials. Finally, we are developing monomers with minimal polymerization shrinkage and applying ring-opening polymerization methods to obtain practical expanding monomers. Dimensionally stable polymerizations are important indiverse applications including adhesives, coatings, lithography, microelectronics and strain-free polymers.
