Assistant Professor in Psychology
Institute for Mental Health

Dr Isabel Morales-Muñoz is Assistant Professor in Psychology based at the Institute for Mental Health, School of Psychology, University of Birmingham. Her main area of research is to investigate risk factors for youth mental health, with a special focus on investigating the role of sleep problems in the development of mental health problems. Her current work is mainly focused on secondary data analyses (e.g. birth cohort studies, such as ALSPAC, Millennium cohort), but she has also expertise in using different scientific methods, including clinical assessments, neuropsychological testing and ERP assessments.

In April 2018, she was awarded the Academy of Finland postdoctoral research fellow, to investigate sleep development in early childhood and the links between sleep and neurodevelopmental and mental health problems in children. In June 2022, she joined the School of Psychology as Assistant Professor, after spending 4 years as honorary research fellow at the Institute for Mental Health, at the University of Birmingham.


Dr Morales-Muñoz is interested in supervising MSc and PhD projects. Potential students can contact her at I.Morales-Munoz@bham.ac.uk.


Research interests

  • Sleep and mental health
  • Sleep and neurodevelopmental disorders (ADHD)
  • Sleep development
  • Early life risk factors for youth mental health
  • Birth cohort studies
  • Epidemiology
  • Neuropsychology and psychosis

Dr Morales-Muñoz conducts research investigating risk factors for the development of mental health problems (e.g. psychosis, anxiety, depression) in young people. More specifically, her current line of research focuses on investigating the role of sleep problems in the development of youth mental health problems. To do this, she uses longitudinal birth cohort studies and data science approaches. Further, she aims to investigate the underlying mechanisms of the associations between sleep and mental health problems, such as brain mechanisms or inflammatory markers. The ultimately aim of her research is to design sleep intervention programs to improve youth mental health.
