Toshi Tomoda, MD., Ph.D.


Dr. Toshi Tomoda is a Project Scientist in the Department of Neurobiology of Depression and Aging. He leads the research group focusing on brain homeostasis regulation in health and brain disorders with affect and cognitive disturbances.

Research Focus


Dr. Tomoda’s primary research question is how affective and cognitive processes are regulated to shape our mind and behaviour in health and brain disorders.

He particularly focuses on cellular and molecular mechanisms for the maintenance of functional homeostasis of cortical circuits underlying normal neurotransmission and neuroplasticity. He studies how disrupted homeostasis of cortical circuits (through, for example, attenuated autophagy, elevated ER stress, disrupted proteostasis, neuroinflammatory changes) may manifest as maladaptive circuit changes, such as excitatory/inhibitory imbalance, leading to affect and cognitive disturbances commonly observed across neurological and neuropsychiatric conditions.

His lab uses cell type-specific circuit manipulation coupled with functional analysis tools in rodent models, and human biopsied samples for correlative studies.
