Research Focus Areas

Social Inequities in Oral Health

diversity_3

We focus on reducing social inequalities in oral health by evaluating the equity impacts of interventions and ensuring that the lived experiences of disadvantaged communities inform policy decisions.

Current Projects

check_circleEvaluating the impact of poverty reduction policies on oral health
check_circleInvestigating trajectories of social disadvantage in adulthood
check_circleUnderstanding oral health inequalities across the life course

Integrating Primary Prevention in Universal Health Coverage

health_and_safety

We explore pathways to achieve universal health coverage for oral health, using high-level simulation models to design affordable, prevention-focused systems accessible across the lifespan.

Current Projects

check_circleCost-effectiveness analysis of preventive dental care
check_circleSimulation modelling of universal dental coverage schemes
check_circleAssessing affordability barriers to preventive care access

Oral Health and Healthy Ageing

elderly

Our work on healthy ageing examines the interrelationship between social disadvantage, oral health, and ageing outcomes to reduce inequities in later life.

Current Projects

check_circleLongitudinal pathways between tooth loss and cognitive decline
check_circleOral health status and frailty in older adult populations
check_circleImpact of lifetime social determinants on healthy ageing

Preventing Incidence of Oral Cancer

medical_services

In cancer prevention, we develop interventions such as tobacco-free generation initiatives, applying causal inference methods to limit new cases of oral cancers.

Current Projects

check_circleEvaluating the potential impact of a tobacco-free generation policy
check_circleCausal analysis of risk factors in oral cancer development
check_circleLong-term outcomes of early disease prevention programs

Reducing Oral Health Related Multimorbidity

monitor_heart

We investigate oral health-related multimorbidity, evaluating strategies to reduce the joint burden and inequitable distribution of oral health-related conditions.

Current Projects

check_circleSocial pathways of oral health-related systemic morbidities
check_circleDesigning health systems to address complex multimorbidity
