Dr Timothy Rittman BMBS BMedSci PgCertMedEd MRCP(London)


I work with patients suffering from Progressive Supranuclear Palsy (PSP) and Corticobasal Degeneration (CBD) in collaboration with James Rowe. These are two rare types of dementia with similarities to Parkinson's disease and Alzheimer's disease. My main interest is functional brain connectivity (how bits of the brain talk to each other), in particular the application of graph theory and independent component analysis. I use fMRI and MEG data for this purpose and I develop computer models of disease processes to help understand how they might affect brain networks. I am interested in what we can learn about PSP and CBD from network connectivity, in particular bridging the gap between pathological changes and cognitive changes of disease.

I also perform saccadometry (measuring a certain type of fast eye movement) in PSP, CBD and Parkinson's disease with a focus on inhibitory pathways.

I hold a Medical Research Council Clinical Research Training Fellowship.
