About

Bio

I am a senior consultant at a 2000 bed public sector inpatient facility in southeast Asia. Broadly speaking, my main areas of interest are in eduction and the care of disadvantaged patients. I have spent the majority of my career in the public sector, having worked in indigent, native American, migrant and rural health care. I have also spent extensive time in both equatorial and southern Africa doing HIV/AIDS, TB, paediatrics, infectious disease, parasitology and tropical medicine. I love teaching patients and junior staff, and derive great satisfaction caring for patients who are unable to obtain their care from mainstream sources. I have also done original research and publishing, and continue ongoing work in these areas.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
