## Overview

### Background

Diep Ha is a dentist and a mid-career researcher at the UQ School of Dentistry. She completed her PhD in Oral Epidemiology at the University of Adelaide. Relative to opportunities, Diep Ha has made exceptional contributions to the national population-based research programs in child oral health. Her contribution was evidenced in research leadership as a Chief Investigator in three successful NHMRC projects, in intellectual input to development of new data collection instruments such as questionnaires, oral epidemiological examination protocols.

Diep Ha is interested in conducting population-based research investigating complex interactions between multilevel determinants of oral health. Her current focus is on effects of fluoride use, dietary patterns on oral health, improve oral health that lead to better health, quality of life and reducing inequality among vulnerable populations.

Diep Ha is currently supervising several PhD, Master by research and Honours students. She currently mentors a team of ECRs in conducting the two projects, of which she is a Chief Investigator.
