Research and scholarly activities
Current research
Polymeric materials find many applications in the dental and biomedical
fields. Our research efforts are focused on the design, synthesis and
characterization of materials intended as permanent dental restoratives or
biodegradable polymers with the potential to be applied in periodontal
regenerative protocols. Analytical techniques coupling polymer conversion and
property evolution help advance the understanding of such materials, and that
has been accomplished with customized optical mounts. Polymerization
induced phase-separation and self-assembly are being used as platforms to
create nano-heterogeneous materials, with increased conversion and reduced
stress. Tailorable polymer particles, incorporating a wide array of functionalities,
are being synthesized and successfully used to reduce shrinkage and stress in
dimethacrylate networks.
Current research interests
1. Polymeric dental and biomedical materials
a) Low shrink / low stress dental composites
b) Biodegradable periodontal materials (membranes/bone graft
materials)
2. Development of new tools to evaluate property evolution in dental
materials
a) Conversion-dependent polymer property evolution
b) High throughput combinatorial analysis
