Introduction
I am an Associate Professor at the School of Psychological Science at UWA and an autism researcher. I completed my DClinPsy at the IOP in London in 2006 and my PhD in early interventions in autism in 2005 with Prof. Patricia Howlin. I am interested in the assessment, identification, diagnosis and supports for autistic youth and adults; masking/ camouflaging in autism; autistic people's mental health and well-being and the factors contributing to it, with focus on anxiety.

Previous studies have suggested that autistic adults may be negatively affected by the COVID‐19 pandemic and its associated restrictions. In this study, we examined continuity and change in loneliness and stress, and their predictors, in 448 autistic and 70 non‐autistic adults living in the Netherlands. Autistic participants were assessed on three...

Lay abstract: Autistic university students have many strengths. They also go through difficulties that professors may not understand. Professors may not understand what college life is like for autistic students. They might judge autistic students. A team of autistic and non-autistic researchers made a training to help professors understand autist...
Chapter
Cognitive behavior therapy (CBT) is a goal-focused, usually short-term therapy that integrates cognitive and behavioral modalities. CBT aims to change unhelpful thinking patterns and behaviors and develop more balanced ways of thinking about, and responding to, distressing experiences and situations. As rates of mental health difficulties are high...
Preprint
Many autistic people develop camouflaging strategies to mask or compensate for their underlying autism-related differences in order to get by in predominantly non-autistic societies. Autistic adults have described camouflaging as a “lifetime of conditioning to act normal”, suggesting that camouflaging develops over the autistic person’s lifespan. Y...

Article
As global rates of diagnoses of autism spectrum disorder (ASD) rise, so too will the number of young adults with ASD who are conscripted into National Service (NS) programs. Given the current lack of studies investigating how NS programs can support and cater to such individuals, and how young people can be supported and prepared for NS, this preli...
Article
Anxiety is common in autism spectrum disorder. Many anxiety symptoms in autism spectrum disorder are consistent with Diagnostic and Statistical Manual of Mental Disorders (5th ed.) anxiety disorders (termed “common” anxieties), but others may be qualitatively different, likely relating to autism spectrum disorder traits (herein termed “autism-relat...

Chapter
Although ASD is a lifelong neurodevelopmental disorder, considerably less emphasis has been paid to assessing, understanding, monitoring and supporting the development of individuals with ASD throughout later adolescence and adulthood. Outcomes in adulthood for many individuals with ASD are so far reported to be poor, although highly variable, whil...
Chapter
Although thousands of research studies have been published relating to the diagnosis, assessment, development, and treatment of children with autism spectrum disorder (ASD), only a very small number have focused on long-term developmental trajectories and outcomes in adulthood. This chapter focuses on what is known about adult outcomes in terms of...
Article
Full-text available
There is growing research evidence that subclinical autistic traits are elevated in relatives of individuals with autism spectrum disorder (ASD), continuously distributed in the general population and likely to share common etiology with ASD. A number of measures have been developed to assess autistic traits quantitatively in unselected samples. So...
Poster
Full-text available
Background: There is increasing research evidence that individuals with a diagnosis of ASD lie at the extreme end of a continuum of quantifiable autistic traits and that there is moderate to high heritability of these traits in child, adolescent and adult community samples. Given this shift towards a dimensional conceptualization of ASD, a range of...
Article
Anxiety-related problems are among the most frequently reported mental health difficulties in autism spectrum disorder. As most research has focused on clinical samples or high-functioning children with autism spectrum disorder, less is known about the factors associated with anxiety in community samples across the ability range. This cross-section...
Article
The high prevalence of anxiety symptoms in individuals with autism spectrum disorders has now been well documented. There is also a positive relationship between autistic traits and anxiety symptoms in unselected samples and individuals with anxiety disorders have more autistic traits compared to those without.
