Dr Mari Dominguez holds an honorary position as Clinical Teacher in Child and Adolescent Psychiatry at Faculty of Medicine, Imperial College London. She works as Consultant Child & Adolescent Psychiatrist at Collingham Child & Family Centre, a National T4 CAMHS Inpatient unit for children (aged 6-12) - NHS England (CNWL, Central and West London NHS Foundation Trust).


Dr Dominguez graduated in Medicine at the University of Navarra (Pamplona, Spain), completed her specialist clinical training in Psychiatry (Hospital Santiago, Vitoria, Spain) and began her academic career in Neuroscience (University of Basque Country, Spain). In 2006, Dr Dominguez obtained a Marie Curie Early Stage Research Training Fellowship, and moved to Maastricht University (Netherlands), where she developed her research interest and expertise in psychiatric epidemiology & meta-analytic studies in the field of adolescent psychosis research. After obtaining her PhD entitled 'A Dynamic Model of the Onset of Clinical Psychosis from an Epidemiological Perspective' in 2009, she continued to work as a Postdoctoral Researcher at Maastricht University. In 2010, Dr Dominguez obtained an Alicia Koplowitz Fellowship (research and clinical fellowship in child and adolescent psychiatry) at Imperial College London (London, UK) where she continued her research work in adolescent clinical psychosis. From 2014 to 2020, Dr Dominguez was the president of the "Association of Scientists in Child and Adolescent Mental Health - Alicia Koplowitz Foundation". 

Dr Dominguez's research examined the psychosis phenotype and investigated the dynamic process driving psychosis expression from mental wellness to onset of clinical psychosis. From examining the dimensional structure of psychosis in the general population, her work expanded to investigate the developmental expression of psychosis in clinical samples of adolescents, as an age period associated with increased risk for the emergence of psychosis, examining treatment delay and pathways to care during adolescence. The significance of her research work had been reflected in first author publications in international peer-reviewed journals and oral presentations at international conferences in psychiatry (SIRS-2008, AEP-2008, ICOSR-2009, SIRS-2010, IEPA-2010, EPA-2014) and child and adolescent psychiatry (RCPsych-2001, AEPNYA-2011, IACAPAP-2012, ESCAP-2013, ESCAP-2015). In 2014, she was awarded the 2014 European Psychiatry Association research prize for the best scientific paper in child and adolescent psychiatry for the work on 'Duration of untreated psychosis in adolescents: ethnic differences and clinical profiles'. 

Dr Dominguez completed the Postgraduate Certificate in University Learning and Teaching at Imperial College and was awarded The Rees Rawling PGCert ULT Prize (2012). She is committed to undergraduate and postgraduate teaching, as reflected on the academic posts and teaching responsibilities hold at the Spanish National Open University (2007-2011), Maastricht University (2009-2010), Imperial College London (2010-present) and New York University in London (2016-present).
