Alexander Lebedev

Research description

With background in psychiatry and data science, Dr. Lebedev is currently working as a research specialist at the Department of Clinical Neuroscience. He is involved in several projects utilising advanced methods of quantitative modelling to study neural mechanisms of belief formation, as well as effects of global socioeconomic trends on population health and wellbeing. Apart from this, Alexander coordinates the brain imaging arm in the PSIPET clinical trial investigating psilocybin's potential to treat major depression (EudraCT: 2020-002790-94).

Research Interests: belief formation, socioeconomics, socionomics, resilience
