Lecturer in Cognitive and Biological Psychology 

After completing a degree in Psychology and Cognitive Neuroscience at the University of Nottingham, Leah went to Bangor University and obtained an MSc in Clinical Neuropsychology in 2012 and a PhD in Neuropsychology in 2015.

Since then Leah has worked in research and teaching roles at Bangor University and the University of East Anglia, before joining UCFB in 2017. She has worked on a range of research projects, which has allowed her to develop a broad skillset involving a variety of quantitative neuropsychological research methods (EEG, fMRI, tDCS, visual half-field tests, dichotic listening tests).

Area of expertise
  • Biopsychology;
  • Limb preference;
  • Motor control.
Teaching & research interests

Leah's research interests involve brain and body asymmetries, such as hand/foot preferences, and their relationship to the location of functions such as language and face perception in the brain. Her teaching is mostly focused on biological/cognitive psychology and how it affects sportspeople, as well as quantitative research methods. At UCFB Leah leads on biological psychology modules, as well as conducting seminars and guest lectures on research methods modules.
