Tissue engineering, cell biomaterial interactions, polymer reaction engineering, computational modeling of branched and crosslinked polymer systems


Our research focuses on the coupling of computational models of hydrogel formation and experimental design for the synthesis of hydrogel nanoparticle delivery vehicles and the fabrication of synthetic hydrogel extracellular matrix analogues with tunable degradation rates, incorporated biofunctionality, and mechanical properties for guiding cell behavior and tissue regeneration. We hypothesize that dynamic kinetic models of polymerization and gelation provide a bottom-up engineering approach to effectively guide in the experimental design and optimization of biomaterial properties for regenerative medicine applications.

Current Research Projects

  • Quantitative analysis of the effects of biofunctional and physical gradients on endothelial cell behavior in poly(ethylene glycol) diacrylate hydrogels
  • Independent tuning of matrix properties for controlled invasion and vessel formation within matrix metalloproteinase-sensitive PEG hydrogels
  • Effects of growth factor loaded PEG nanoparticles on cell invasion and vascularization within synthetic PEG ECM analogues
  • Crosslinked PEG nanoparticles for sustained delivery of phosphate ions to the intestinal mucosa
  • Computational modeling of hydrogel crosslinking via free-radical photopolymerization for the prediction of PEG ECM analogue biomaterial properties
