Research

My expertise lies in translational research in Biomaterials and Regenerative Medicine. I am currently interested in developing novel scaffolds and hydrogels derived from both natural and synthetic resources suitably modifying them to improve their functionality and biocompatibility to enhance the rate of bone regeneration.

My projects include:

  1. Development of a smart toothpaste for improving oral hygiene and implant longevity
  2. Development of a novel bioactive hydroxyapatite bone substitute from NZ sourced bovine bones for bone regeneration
  3. Development of bioactive biocomposites for bone regeneration and dental repair
  4. Ionic substitutions in synthetic hydroxyapatite
  5. Development of novel temperature-sensitive hydrogels for bone tissue engineering

Additional details

I am passionate about volunteering in the mental health space focused on providing better mental health support to researchers and students, and creating men's mental health awareness.
