Personal profile

Research engagement

In order to disseminate research broadly, each year I participate in a handful of media interviews and public discussions. As examples, in 2018, I published a piece in The Conversation on hoarding disorder and delivered an informal presentation on how to conquer fear and anxiety for Nerd Nite North Sydney. In 2019, I delivered a sold-out public talk (The Science of Hoarding) at the State Library of NSW for the Sydney Science Festival during National Science Week.  I am also actively involved in disseminating scientific knowledge creatively through non-research forums. For example, in 2019, I joined comedians Tom Ballard and Jordan Raskopoulos to discuss The Trauma Cleaner on Audible's What's the Story.

In addition to furthering my lab's research agenda, I also help facilitate others' research by serving as an ad hoc reviewer for multiple journals and by serving on the Editorial Boards of Behaviour Research and TherapyBehavior Therapy, and Current Opinion in Psychology. I am currently serving as an Invited Guest Editor for a special issue on Object Attachment for Current Opinion in Psychology. This special issue is quite exciting because it brings together research from various fields in psychology, as well as from psychiatry, marketing, and design to develop a comprehensive understanding of the causes and consequences of object attachment. 

Research student supervision

I routinely supervise both undergraduates and postgraduate students interested in topics related to my field of research. Importantly, many students enter my lab before the Honours year as a way to prepare themselves for their upcoming year of research. I also mentor postdoctoral fellows in their supervision of students by serving as a co-supervisor.

I grew up in a small, rural town in Nebraska. I did not grow up thinking that I was smart. In high school, I opted for classes that seemed easy. Through what seemed like luck, rather than intellect, I became the high school yearbook editor. Becoming editor of the yearbook encouraged me to obtain a university degree. While at the University of Nebraska-Lincoln, I took a “Careers in Psychology” class that put me on the path to becoming an academic clinical psychologist. That class taught me that it could be a long and competitive path. So, I followed its advice. I worked hard to simultaneously maintain a high GPA, volunteer for clinical experience, and gain research experience. Part of my research experience was made possible by the McNair Scholars Program, which is designed to prepare disadvantaged undergraduate students for doctoral studies. If it was not for the McNair Scholars Program and other opportunities provided to me by academic and clinical mentors, I may not be where I am today. Thus, it is very important to me that I give back to other first-generation minority students.  I am currently a member of the Waranara mentoring program for Indigenous students and am working with other psychology academics to increase equity and inclusion at MQ. 

In 2016, I became Deputy Director of the Centre for Emotional Health. Amongst other priorities, one strategic objective I lead within the CEH is to prepare world-ready HDR candidates, early career researchers, and clinicians. To do so, I facilitate a mentoring group that all CEH students can attend, including Honours students. I help these students to discover their long-term career plans and in developing and meeting goals that will help them achieve their aspirations. The group also provides an avenue for receiving support as furthering one's education is not always easy.

In regard to research, my interests are within the field of clinical psychology. Broadly speaking, my aims are to discover what factors and processes contribute to the aetiology and maintenance of anxiety, obsessive-compulsive and related disorders, and substance use problems. I am interested in the role of both general (e.g., interpersonal difficulties and perceived distress intolerance) and disorder-specific factors (e.g., object attachment in hoarding disorder). Another aim of my research is to find solutions for improving treatment outcomes and decreasing relapse after treatment. Although behavioural and cognitive-behavioural treatments are effective at reducing a variety of unwanted behaviours, not all benefit and relapse is common.

I additionally hope to reduce overconsumption in Australia and throughout the world by using and adapting my research on hoarding disorder and addiction to fit the broader population.

In addition to my other roles, I maintain a small private practice through the CEH-Clinic. I am a Registered Psychologist with clinical endorsement (AHPRA Registration Board Registration No: PSY0001352136) and a board approved supervisor (clinical psychology). 


I am responsible for teaching and convening PSY337 (Psychopathology) and PSYC987 (Child and Adult Psychopathology 1). I also teach on PSYC104 (Introduction to Psychology I), PSYC988 (Psychological Assessment and Child and Adult Psychopathology 2), and PSYC989 (Clinical Psychology Therapy 2).

Community engagement

I am engaged in a number of activities within the community. For example, I am the current President for the Australian Association for Cognitive and Behaviour Therapy, a national professional body for health and other professionals interested in evidence-based behavioural and cognitive therapies. In 2017, I served as Convenor for its annual conference and from 2017-2019 served as Treasurer for the Association.  I am also a member of the Sydney North Health Network Mental Health Advisory Committee.
