Research Interests

My area of research is in the dental/craniofacial and orthopaedic alloys, corrosion/degradation and surface modification/coatings, bone cell mechanics and in chitosan-based materials for implant coatings, bone tissue engineering/regenerative medicine engineering and drug delivery. Current active research is focused on design and development of chitosan-based materials and composites for; dental and orthopedic implant coatings, composites for bone grafts, injectable micro- and nano- particles for tissue scaffolds/templates and drug delivery, and wet-spinning, electrospinning and electrospraying of fibers/membranes/coatings. Research encompasses bulk and surface materials properties, in vitro and in vivo biocompatibility testing using wide range of cells including macrophage, fibroblast, osteoblast and endothelial cell cultures and rodent soft and hard tissue models.
