I am a researcher at University College London, Division of Psychiatry. As part of the European Medit-Ageing Research Group, I investigate the impact of meditation training on mental health and well-being in the ageing population. I am also leading the IMPRINT project, which aims to deepen and refine the relationship between meditation and psychedelic research. 


I have received my BSc in Psychology from the University of Groningen, my MSc in Clinical Mental Health Sciences from University College London, and research training at McGill University. I have been awarded a fellowship from the German Academic Scholarship Foundation (Studienstiftung des deutschen Volkes). I am currently completing a PhD in psychology at the University of Geneva. I have spent one year on silent meditation retreats.

Research Summary

I contribute to developing frameworks for understanding and investigating meditation training and its mechanisms in the context of the Medit-Ageing Project. We have completed a large randomised trial to investigate the effects of an 18-month meditation training on brain and mental health in the ageing population (protocol: Poisnel et al. 2018). I am currently working on manuscripts that evaluate the effects of our intervention on well-being, personality, and psychological risk factors for cognitive decline. We are also trying to understand the impacts of mindfulness and compassion meditation on brain, cognitive, and ‚Äčemotional processes in expert meditators (protocol: Lutz et al. 2018). My research has included the study of meditation-related difficulties and ways to address theoretical, methodological, and clinical issues that arise in the context of such difficulties (Schlosser et al. 2019). I regularly review manuscripts on meditation research. Scientific journals have included Acta Psychiatrica Scandinavica, Mindfulness, Plos One, Current Psychology and the Journal of Consciousness Studies.

I am leading the IMPRINT project (Integrating Meditation and Psychedelic Research Initiative). I am currently preparing a theoretical paper on psychedelic-assisted meditation training. At UCL, I co-supervise several BSc and MSc dissertation projects that focus on psychedelic research. 

Healthy ageing
As part of the Marchant Lab at UCL, I investigate psychological risk factors for dementia. In particular, I am interested in the relationship between repetitive negative thinking and Subjective Cognitive Decline (Schlosser et al. 2020a) and in lifestyle habits that may reduce repetitive negative thinking (Schlosser et al. 2020b). We are currently completing an international, randomised trial to test if an 8-week mindfulness-based intervention can support healthy ageing in individuals with Subjective Cognitive Decline (protocol: Marchant et al. 2018).
