Anja Lok. Associate Professor of Youth Affective Disorders: Improving Outcomes through the Exposome and Art-Science Integration | Psychiatrist | Principal Investigator, MoodLabMeets | Amsterdam UMC & Swammerdam Institute of Life Sciences

Anja Lok is a psychiatrist and psychologist whose work reconceptualizes affective disorders in adolescents and young adults as exposome-shaped conditions, emerging from dynamic interactions between neurodevelopment, immune–metabolic and microbiome systems, and social–environmental stressors. Her clinical and scientific work is grounded in the recognition that adolescence and young adulthood are periods of profound neurobiological plasticity and vulnerability, in which early intervention can meaningfully alter long-term mental health trajectories.

As psychiatrist and principal investigator, she integrates transitional psychiatry, systems neuroscience, and population-based epidemiology with mechanistic and art–science–based translational research. A central focus of her work is anhedonia and affective dysregulation during critical developmental transitions, understood not as isolated symptoms but as emergent properties of interacting biological, psychological, and environmental systems.

Transition Center for Affective Disorders (TAS) & MoodLabMeets

Anja is founder and clinical–scientific lead of the Transitiecentrum Affectieve Stoornissen (Transitiecentrum voor Affectieve Stoornissen (TAS) | Amsterdam UMC) at Amsterdam UMC, a specialized center for youth aged 15–25 that bridges child and adult psychiatry. TAS serves as a platform for early detection, personalized diagnostics, and innovative interventions, including neuromodulation and novel psychobiological treatment strategies. In parallel, she is principal investigator of MoodLabMeets, where she develops exposome-informed, developmentally grounded interventions that explicitly link biological mechanisms, embodied experience, and environmental context.

Swammerdam Institute of Life Sciences (SILS) and the Amsterdam Microbiome Expertise Center (AMEC).

Her interdisciplinary background spans psychiatry, psychonomics, and biological psychiatry, with a strong emphasis on metabolic psychiatry—investigating how energy metabolism, inflammation, and hormonal dynamics intersect with mood disorders. Her research ranges from hormonal and metabolomic studies to work on the human microbiome as a key modulator of brain function and mental health. Positioned at the nexus of the exposome and psychobiological functioning, the microbiome is a central focus of her collaborations with the Swammerdam Institute of Life Sciences (SILS) and the Amsterdam Microbiome Expertise Center (AMEC).

Arts-based learning

Beyond conventional biomedical approaches, Anja integrates arts-based science and experience design into both research and clinical practice, aiming to enhance affective and cognitive flexibility and to support young people in reconnecting with pleasure, creativity, and agency. Her neuroscience-informed work on jazz improvisation explores spontaneous creativity under conditions of uncertainty and time pressure as a model for dynamic brain–body regulation. Through museum collaborations, interactive media, and initiatives such as Art in Science@AmsterdamUMC, she actively translates scientific knowledge into public engagement
