Education

Postgraduate

2013-18 PhD (Statistics), Queensland University of Technology. Supervisor: Kerrie Mengersen.

Award APA ($24,500 Annually for 4 years) ; IDTC Top Up ($10,000 Annually for 4 years) .

Research Research covers model-based exploration methods of missing data, Bayesian longitudinal modelling of individual and group health in a mining site, optimal placement of Automatic Electronic Defibrillators (AEDs), modelling geospatial cardiac risk, and the production of R packages to facilitate research impact.

Undergraduate

2008-12 B. PsychSc (Honours), University of Queensland. Supervisor: Philip Grove.

Research Conducted psychophysical research on whether sharpness of a leading edge in a 3D environment improves under specific scenarios of monocular occlusion in the thesis: “How Sharp is Sharp?: The Effect of Monocular Texture on Enhancing Sharpness.” Awarded first class honours.

2010 Exchange semester, McGill University. Studied History of Personality Theory, Abnormal Psychology, Psychology of Interpersonal Relationships, Ethics, and Intermediate French.
