My research develops mathematical, statistical, and computational methods for strengthening scientific inference about latent psychological, behavioural, and health-related phenomena. Many of the processes studied across psychology and the health sciences cannot be observed directly, requiring researchers to infer them from measurements, behavioural observations, statistical models, and other empirical representations. My work investigates how hidden assumptions embedded within these representations influence scientific conclusions and develops methodological frameworks that improve the validity, transparency, and interpretability of empirical inference.
I was originally trained in quantitative psychology, specialising in mathematical models of eyewitness identification and cognitive decision-making. This work demonstrated how competing theoretical models can produce observationally equivalent predictions and established my continuing interest in developing critical empirical tests capable of distinguishing between alternative scientific explanations. Since then, my research has expanded to psychometrics, network science, epidemiology, and machine learning, while remaining centred on the methodological foundations of scientific reasoning.
Much of my current research uses oral epidemiology as a methodological laboratory for investigating problems of measurement, observability, and inference in progressive systems. Periodontitis provides a particularly informative example because disease progression progressively removes the structures through which cumulative disease is measured. My work develops methods for reconstructing latent disease burden under informative missingness using spatial modelling, network analysis, statistical learning, and formal estimand frameworks. Although motivated by periodontal disease, these methods address general problems encountered across psychology, epidemiology, and other observational sciences whenever the phenomenon under study influences what can be observed.
A complementary area of my research focuses on psychometric evaluation and educational research. I have applied network psychometric methods to investigate the structure of perceived social support and the psychological impacts of COVID-19, while more recent work evaluates cultural safety education in collaboration with Aboriginal researchers and educators. This research examines how educational interventions influence student learning, confidence, and reflective practice, with the aim of strengthening culturally responsive health education through rigorous quantitative evaluation.
Looking forward, I aim to extend this research programme to increasingly complex behavioural data, including language, cognition, and human decision-making. By integrating natural language processing, network science, machine learning, and mathematical modelling, I seek to develop more transparent methods for understanding latent cognitive processes while continuing to advance methodological approaches applicable across psychology, epidemiology, and the health sciences.

Research Interests

My current research is organised around four interconnected themes that investigate how complex psychological and health-related phenomena can be more accurately measured, represented, and interpreted.

Measurement in Progressive Systems

A major focus of my research examines how progressive disease processes influence what can be observed and, consequently, how disease burden should be measured. Using periodontitis as a model system, I develop methods for reconstructing cumulative disease burden when severe disease results in tooth loss and conventional measures no longer reflect lifetime disease experience. Current work includes estimand development, cumulative burden measures, tooth-level reconstruction, and sensitivity analyses under alternative assumptions about informative missingness.

Spatial, Network, and Machine Learning Approaches

I develop computational methods that exploit spatial structure, anatomical relationships, and network topology to improve disease measurement and prediction. This includes spatial modelling of tooth-level disease, network representations of disease progression, machine learning approaches to reconstruct missing information, and graph-based methods for understanding the organisation of complex biological systems.

Psychometrics and Educational Evaluation

A complementary research stream applies quantitative psychological methods to measurement and evaluation in health education. Current projects include network psychometric analyses of psychological constructs, evaluation of cultural safety education in collaboration with Aboriginal researchers and educators, and the development of quantitative approaches for assessing educational outcomes, confidence, and reflective practice.

Population Oral Health and Health Inequalities

My methodological research is applied to large population datasets to better understand oral health inequalities, chronic disease, multimorbidity, ageing, and access to care. I am particularly interested in developing measurement approaches that more accurately represent people with advanced disease, older adults, and populations whose health burden may be underestimated by conventional epidemiological measures.

Future Research

My future research will continue to extend methodological approaches for understanding complex psychological and health-related systems. Current priorities include developing generative models of disease progression, integrating causal inference with machine learning, and extending reconstruction methods to longitudinal data. I also intend to expand my work in quantitative psychology by applying natural language processing, network science, and mathematical modelling to the study of cognition, language, and human decision-making.

Across these areas, my long-term objective is to develop generalisable methodological frameworks that improve the validity, transparency, and interpretability of scientific evidence across psychology, epidemiology, education, and the health sciences.

Teaching Philosophy

My teaching philosophy is founded on the belief that research methods should be taught as a process of scientific reasoning rather than as a collection of statistical procedures. The purpose of research methods education is not simply to teach students how to perform analyses, but to help them understand how scientific conclusions are constructed, justified, and critically evaluated. Students often learn statistical techniques without fully appreciating the assumptions that underpin them or the scientific questions they are capable of answering. My aim is therefore to help students develop the judgement required to select, evaluate, and interpret methods critically, rather than simply apply them correctly.

Across my teaching, I present research as a sequence of interconnected decisions linking theory, conceptualisation, measurement, analysis, and inference. By understanding how each stage shapes the next, students learn that statistical methods are not ends in themselves but tools for investigating psychological phenomena. I encourage students to view research as a process of developing and evaluating competing explanations, recognising that valid scientific inference depends upon the alignment of theoretical questions, measurement strategies, analytical methods, and interpretation.

My teaching draws heavily on authentic methodological problems arising from my own research, including model identifiability, psychometric structure, informative missingness, and measurement distortion. Rather than asking only whether an analysis has been performed correctly, I encourage students to ask whether the chosen approach faithfully represents the phenomenon under investigation, whether its assumptions are justified, and whether the resulting evidence supports the conclusions being drawn. I have found that connecting abstract statistical concepts to real research problems strengthens students' quantitative confidence while fostering deeper engagement with scientific reasoning.

This philosophy has informed my teaching across undergraduate, honours, and postgraduate psychology, including research methods, statistics, and perception and cognition. It has also guided the development of online R training resources, supervision of honours and postgraduate research projects, evaluation of educational outcomes, and individual statistical consultation. Most importantly, I aim to create an inclusive learning environment in which students from diverse educational, cultural, and disciplinary backgrounds feel confident engaging with quantitative methods, recognising that scientific thinking develops most effectively when students are supported to question assumptions, learn from uncertainty, and participate actively in the process of discovery.

Ultimately, my goal is to contribute to research methods education that equips future psychologists not only with technical competence, but with the capacity to evaluate evidence critically, distinguish between competing scientific explanations, and make rigorous, transparent, and defensible scientific inferences throughout their careers.
