Loc is currently Director of Research at the School of Dentistry, University of Queensland.

Research funding: Currently, he is the Chief Investigator A of four major NHMRC- and MRFF-funded research projects: a population-based birth cohort study investigating impact of socioeconomic inequality on child oral health, a longitudinal study investigating effect of early life exposure to fluoride, a study to investigate effectiveness of water fluoridation in Queensland, and a study to develop and implement a package to improve oral health in residents of Aged Care Facilities in Queensland and NSW.

Qualifications: BDS, MScDent, PhD

Research Interests: Oral epidemiological measurement of dental diseases Quantitative analysis of oral epidemiological data including multilevel analysis Risk and benefit trade-off in the use of fluorides in children Natural history of dental fluorosis Socio-economic inequality in oral health Oral health-related quality of life Smoking as a risk factor for periodontal diseases Effectiveness and safety of water fluoridation in children Complex systems science in dental research.

Awards and Honours: In 2025, Loc is the recipient of the International Association for Dental Research (IADR) Distinguished Scientist John Greenspan Global Oral Health Research Award. In 2022, Loc is the recipient of the International Association for Dental Research (IADR) Distinguished Scientist H Trendley Dean Award 2022.
