Meet the APRA team

Kenan de Leeuw
Chair of the Board
Kenan de Leeuw is the chair of APRA, where he has been an active member since 2019. He has a background in clinical neuropsychology and works as a psychologist and researcher at Jellinek Amsterdam, where he treats patients suffering from addiction and co-occurring psychiatric disorders. He primarily works with Acceptance & Commitment Therapy (ACT) and trauma-informed mindfulness practices. Currently he is leading a research project for a pilot study investigating Psilocybin-assisted ACT (PACT) as a novel, integrative treatment for severe alcohol use disorder. Kenan has a broad interest in psychoactive drugs and non-ordinary states of consciousness, the neuropsychology of addiction, intersections between psychotherapy and Buddhist philosophy and therapeutic use of music. Finally, he is an advocate for progressive drug policy and harm reduction initiatives.

Emily Duckett
Vice Chair / Treasurer
Emily Duckett serves on the board of APRA as Treasurer and Head of Events. She completed a Research Master’s in Linguistics and Communication from the University of Amsterdam. While she is broadly interested in psychoactive substances and altered states of consciousness, she is particularly fascinated by the intersection of language, psychedelic experience, and AI. She aims to pursue research using natural language processing tools to develop better methods for measuring and understanding these experiences, in order to deepen scientific understanding and explore their potential to enhance well-being. Emily also has experience working at House of Smart, providing her with practical knowledge of psychedelic use and harm reduction in a smartshop setting.

Stijn Janssens
Secretary
Stijn Janssens serves as Secretary of the Board of APRA. He is a student of psychology with a strong interdisciplinary interest in philosophy of mind, metaphysics, phenomenology, neuroscience, artificial intelligence and religious studies. He is interested in altered states of consciousness as an experimental tool to apply and investigate concepts that have previously been very difficult to study or manipulate. His interest in psychedelics mainly stems from these fundamental questions, examining what such experiences reveal about consciousness, the self, and reality. In his free time, Stijn likes to create interdisciplinary video essays on topics ranging from comparative religion and mathematics to ancient Greek intertextuality and the archaeology of the Western Sahara. He also enjoys listening to, playing and composing classical music.
