Teaching

I currently teach clinical pharmacy at undergraduate level. I coordinate a full paper PHCY 473 (full year, 28 hours contact time, 25 hours paper coordination role). In addition, I also coordinate the central nervous system module in the quality use of medicines module, PHCY 473 (full year, 15 hours contact time, 20 hours coordination role).

Research

I have established my own pharmacoepidemiology research group funded by multiple research grants (otago.ac.nz/ripe). I am a Registered Pharmacist in Australia, Associate of the Australian College of Consultant Pharmacy, and Member of the International Society of Pharmacoepidemiology. I hold consultant roles in professional practice in Australia for over a decade.

My research focus includes:
  • Quality Use of Medicines
  • Geriatric Pharmacotherapy
  • Psychotropic Pharmacotherapy
