I am a clinical psychologist and Associate Professor at the Australian Catholic University, School of Behavioural and Health Sciences, Strathfield campus. I have more than 20 years of clinical experience as a registered clinical psychologist and provide treatment for people with obsessive-compulsive and related disorders (including hoarding disorder). I obtained Bachelor of Social Science degree with Honours in psychology from the National University of Singapore in 1995 and completed his Doctor of Psychology (DPsych) degree at the University of Melbourne in 2002. I have subsequently worked as a clinical psychologist in a psychiatric hospital in Melbourne, Australia until 2009. From 2009 to 2015, I ran the RMIT university psychology clinic as the clinic director. In 2015, I commenced an academic position at ACU to teach and coordinate the Master of Psychology course. I am currently the National Course Coordinator for psychology postgraduate courses in ACU. These clinical and teaching roles have sparked an increasing interest in clinical research. My research interests are in the area of clinical psychology and with a focus on obsessive-compulsive and related disorders, including hoarding disorder, OCD, and compulsive buying. I am also very interested in examining the application of mindfulness and acceptance-based therapies for these conditions.
