Rebecca Denniss

Doctoral Researcher


I am a cognitive neuroscience Doctoral Researcher investigating the potential effects of micronutrient supplementation on the cognitive rehabilitation outcomes of individuals who have sustained traumatic brain injuries.


I completed my MSc in Cognitive Neuroscience in 2012, earning a distinction, going on to begin my PhD in 2014.

Between completing my Masters and commencing my Doctoral studies I split my time working as an Assistant Psychologist in a neuro-rehabilitation unit and as a Research Assistant at Sheffield Hallam University on a number of projects related to traumatic brain injury.

In 2015 I was part of a team that won the 2015 Mental Health and Wellbeing Medipex award.

I am a member of the British Neuroscience Association.

My research is particularly focused on traumatic brain injury. I also have an interest in all aspects of neurodegenerative diseases.
