Personal profile


I am a Macquarie University Research Fellow and a registered Clinical Psychologist. I completed my PhD and Masters of Clinical Psychology at Macquarie University in 2014, followed by two postdoctoral fellowships at the University of South Florida, Florida and at Macquarie University before beginning my Macquarie University Research Fellowship.

My research is focused on understanding the cognitive and environmental mechanisms that underpin anxiety (and related disorders) in childhood and older age, and whether these factors impact on the efficacy of existing treatments. These interests include how fear learning, cognition, attention and memory impact the development, maintenance and treatment of anxiety problems.

Research interests

  • Cognitive and learning mechanisms underpinning anxiety and related disorders, including fear learning, neuropsychological functioning, and attentional, memory and cognitive and biases.
  • Psychosocial impacts of anxiety and related disorders
  • Treatment of anxiety, depression, obsessive compulsive and tic disorders.
  • Family responses to mental health problems in youth and older adults, including family accommodation, mental health literacy and stigma.
  • Optimising age-appropriate assessment of mental health symptoms, and assessment of treatment outcome.

Research student supervision

I supervise research students with interests in the following areas:

Anxiety; Depression; Children; Adolescents; Youth; Older adults; Cognitive Behaviour Therapy; Treatment; Fear conditioning; Fear Learning; Attention bias; Cognitive bias; Memory; Neuropsychological functioning; Cognition; Family accommodation; Avoidance; Optimising treatment; Novel treatment approaches; Assessment.


I provide guest lectures on the Masters of Clinical Psychology, Masters of Clinical Neuropsychology and Honours programs.

Community engagement

I regularly provide talks on anxiety disorders in youth and older adults to parents, teachers, early childhood workers, aged care workers, health professionals and members of the community. I also engage in a range of media interviews (television, radio and newspaper) about childhood and late-life anxiety disorders.
