Pedro Ribeiro Santiago

BIOGRAPHY AND RESEARCH INTERESTS

My name is Pedro Henrique Ribeiro Santiago and I’m currently undertaking the second year of my PhD at the University of Adelaide. I have a bachelor’s degree in Psychology and a master’s degree in Public Health. In my master’s degree, I investigated the feasibility of a brief mindfulness-based intervention for primary care professionals in the Brazilian national health system. In my PhD candidature, I'm studying the validity and cross-cultural validity of western developed psychological instruments in an Aboriginal Australian population. In addition, I’m also currently working as a data analyst in a project related to Food Frequency Questionnaires and the effects of a randomized controlled trial on dietary patterns and nutrient intake among Aboriginal children.

My research focuses on modern psychometric methods to advance scientific measurement in health and social sciences. My methodological interests include: measurement invariance and differential item functioning; item response theory; structural equation modeling; extended Rasch models; Bayesian inference; modern epidemiology (counterfactuals and potential outcomes, causal inference), among others.
