Our lab focuses on the design and development of chitosan-based materials and composites for:

  • Dental / Craniofacial and Orthopaedic Alloys Corrosion / Degradation studies

  • Surface Modification / Coatings

  • Bone Cell Mechanics

  • Chitosan-Based Materials for Implant Coatings

  • Bone Tissue Engineering / Regenerative Medicine Engineering

  • Drug Delivery.

 

Research encompasses bulk and surface materials properties, in vitro, and in vivo biocompatibility testing using a wide range of cells including macrophage, fibroblast, osteoblast, and endothelial cell cultures and rodent soft and hard tissue models.
