Anatomical Evidence for an Indirect Pathway for Word Repetition

Neurology 2020 

Watch my talk on Youtube: 




I have a double background in Neuropsychology and clinical Neuroimaging, both of which I combine in my current research. My research is at the forefront of mapping the connectional anatomy of cognition to identify inter-individual variability in the structure and function of the brain. I capitalise on exciting new technologies and methods to identify variability within and across populations to formulate novel anatomical cognitive models and improve personalised medicine.

To achieve this goal, my research follows several lines of investigation: 

  • Mapping neurovariability to predict clinical impairments and recovery for precision medicine

  • Anatomical studies of the human brain to map and validate the white matter networks

  • Comparative Anatomy studies to map the evolution of the brain as the foundation of higher cognitive functions
