About Me

A very natural and relaxed conversation with my brilliant Research Assistant, Brier Michelsen
I am an Associate Professor in the School of Psychological Sciences at Macquarie University. I was awarded my PhD in Psychology in 2014, and went on to do postdoctoral fellowships at the University of Minnesota and Macquarie University before being awarded back-to-back fellowships. 

I currently hold an NHMRC Investigator Grant working to improve our understanding of the empirical structure of psychopathology based on the specific patterns in which symptoms of mental disorders tend to co-occur. For example, someone who is depressed is likely to also experience anxiety, and someone who has problems with gambling is likely to also struggle with drug or alcohol use. 

My research uses these patterns in symptoms and disorders to characterise the nature, causes, and consequences of mental illness across the lifespan.
