I came to ANU in July 2011. I was awarded BSc(Hons, 1st class) in 2012 and received PhD in Psychology in 2015. My PhD research has been devoted to understanding the impacts of ambiguous information on causal reasoning and how people may treat ambiguous observations. My current research focuses on (1) developing a new family of distributions for modelling double bounded random variables, and (2) understanding judgment and decision making under uncertainty. I am also conducting collaborative research with international researchers on cross-group measurement invariance.  

Some of my recent research topics include:

  • Causal reasoning under ambiguity
  • Probabilistic reasoning in moral dilemmas
  • Cross-cultural measurement invariance of psychological assessments
  • Modelling doubly bounded random variables
