Professional background

Jason Warren graduated in medicine from the University of Adelaide (BMedSc(Hons) 1990; MBBS(Hons) 1993) and completed neurology training at the National Hospital for Neurology and Neurosurgery and the Institute of Neurology, London (Australasian Fellow 1999; FRACP 2000; PhD 2005). He a Wellcome Trust Clinical Fellow (Intermediate Clinical Fellowship 2006; Senior Clinical Fellowship 2010) and Reader in Neurology at UCL (from 2009). His research is directed toward the systems neuroscience of neurodegenerative disease, using complex sound (including environmental sounds, voices, speech and music) as a paradigm to understand the mechanisms and brain basis for impaired information processing in the dementias. This work employs a range of techniques including psychophysics, neuropsychology, structural and functional MRI.

Research interests

Dr Warren has a particular interest in the progressive aphasias, frontotemporal dementia, and auditory agnosias and related central disorders of complex sound processing. He has a broader clinical interest in the wider field of cognitive and behavioural neurology.
