Background

Alex’s research aims to understand the neural dynamics of how we understand what we see – from when light hits the retina, to an understanding of what we see. Alex completed his PhD at the University of Cambridge in 2011, before research posts at the University of California Davis and the University of Cambridge.

Research interests

  • Semantic memory
  • Perception
  • Brain dynamics
  • Neuroimaging methods

Our brain recognises objects with remarkable speed and accuracy. Alex’s research aims to understand the rapid neural dynamics that enable us to understand what we see. Alex combines different neuroimaging methods (fMRI, MEG, EEG, neuropsychology and ECOG) with cognitive and computational models of vision to ask how visual signals access our semantic memory for objects, in terms of how different brain structures support different kinds of information, and how information in the brain changes over time.

Teaching

Alex teaches on the modules Fundamentals of Cognitive Psychology, Becoming a Researcher, Research Techniques for Psychology, and Learning, Memory and Perception.

Qualifications

  • PhD Experimental Psychology, University of Cambridge
  • MSc Cognitive Neuroscience, University of York
  • BSc Psychology, University of Sheffield
