Research

Niranjan's expertise lies in translational research in biomaterials and regenerative medicine. He maintains a keen interest in developing novel biomaterials derived from both natural and synthetic resources and modifying them to improve their functionality and biocompatibility to promote tissue regeneration.

Niranjan’s current projects include:

  1. Development of a smart toothpaste for improving oral hygiene and implant longevity (funded by Health Research Council NZ)
  2. Development of a novel bioactive bone substitute from New Zealand-sourced bovine bones for bone regeneration
  3. Development of bioactive biocomposites for repairing bone and dental defects
  4. Ionic substitutions in synthetic hydroxyapatite
  5. Development of novel temperature-sensitive hydrogels for bone tissue engineering

Additional details

Niranjan is passionate about facilitating conversations relating to mental health in the university community. Niranjan's campaign in collaboration with Silverline Otago focuses on advocating for better mental health support to students and early career researchers, and creating men's mental health awareness.
