Ali Jannati, MD, PhD
Postdoctoral Research Fellow

Education History:
Ph.D., Cognitive and Neural Sciences , Simon Fraser University, Vancouver, Canada
M.A., Cognitive and Neural Sciences, Simon Fraser University, Vancouver, Canada
M.D.,Tehran University of Medical Sciences, Tehran, Iran

Ali received his MD from Tehran University of Medical Sciences in Tehran, Iran, where he was involved in research studies in neurogenetics, neuropharmacology, cognitive psychology, and neurology. He then pursued his graduate studies in Cognitive and Neural Sciences at Simon Fraser University in Vancouver, Canada, where he studied visual attention, masking, and visual search in healthy adult humans using visual psychophysics, electroencephalography (EEG) and event-related potentials (ERPs).

Ali first joined the BA-CNBS as a Visiting Fellow in 2013, while still in graduate school, to gain experience in applications of transcranial magnetic stimulation (TMS). After completing his PhD training, he returned to the BA-CNBS as a Postdoctoral Research Fellow in December 2014.

Research Interests:

Ali’s long-term interests lie in utilizing techniques in cognitive neuroscience and neurophysiology, including behavioral experiments, EEG/ERP, noninvasive brain stimulation, and functional neuroimaging to improve the understanding, diagnosis, and treatment of neuropsychiatric disorders. At present, he is working on a project that explores the utility of TMS measures of brain plasticity as a novel neurophysiologic endophenotype in high- and low-functioning adults and children with autism spectrum disorders.
