My current research investigates the effects of intensive cognitive training on brain tissue microstructure. Specifically, I am interested in imaging myelin plasticity with magnetic resonance imaging (MRI) in the human brain following intensive training in spatial navigation.
My PhD focused on the anatomy and function of evolutionarily conserved subcortical ‘survival’ pathways in 1) processing emotion and orienting towards non-conscious threat, 2) control of reflexive eye movements and 3) control of sleep, attentional and arousal states.
