Dr Louise Paterson
Assistant Professor
Imperial College LondonDr Louise Paterson is Assistant Professor in Psychopharmacology and Psychiatry at Imperial College London. Her research explores the neurobiological mechanisms underpinning addiction, with a focus on developing neuroscience-informed treatments through experimental medicine, advanced neuroimaging, and clinical trials. Her overarching goal is to deliver transformative interventions that improve outcomes for people affected by addiction. Much of her current work centres on opioid dependence, a critical area of unmet clinical need. She is leading studies investigating neurokinin-1 (NK1) receptor antagonism in reward and emotion-related brain processing, as well as a clinical trial assessing whether baclofen can support methadone detoxification in community-based drug and alcohol services. Dr Paterson’s broader interests include identifying and testing novel pharmacological targets in addiction, such as the GABA-B, D3, orexin-1, and GLP-1/GIP receptors. Her recent work expands into the field of psychedelic-assisted therapy, where she co-leads the NIHR-funded PsilOpioid trial - an innovative study conducted with the Centre for Psychedelic Research at Imperial College. This trial aims to evaluate whether psilocybin therapy can reduce relapse and support early abstinence in individuals recovering from opioid dependence.
