Judy Luigjes research focuses on compulsive disorders: addiction, and obsessive-compulsive disorder (OCD). Her primary motivation is understanding why it is so challenging to stop behaviours that we know are not good for us. While her earlier research primarily delved into the biological and mechanistic aspects of these conditions, Judy has recently expanded to qualitative and clinically applied projects. With this shift in focus she aims to directly influence treatment approaches, especially in the realm of psychotherapy.

Moreover, her current research involves a project that explores the significance of autonomy within the wider field of psychiatry. Judy Luigjes is particularly interested in investigating how autonomy can be enhanced in patients, with the ultimate goal of improving their overall wellbeing. By narrowing the gap between theoretical understanding and practical application, she strives to contribute to the development of more effective and patient-centered therapeutic interventions.
