Fern Jaspers-Fayer

PhD Psychology

Dr. Fern Jaspers-Fayer completed her graduate work at Simon Fraser University and has a keen interest in how the brain processes normal and pathological emotion. She has recorded brain waves (e.g. electroencephalography) and brain pictures (e.g. functional magnetic resonance imaging, fMRI), in people with anxiety, depression and OCD. Dr. Jaspers-Fayer also has a side interest in sleep and biological rhythms, primarily because sleep disruption can influence emotion.
