Brain-bahavior mapping

Spatiotemporal State-Trait Brain Dynamics in the Human Brain

I use resting state fMRI to investigate the state-trait dynamics of the human brain and their relationship to individual bahavior.

Brain Dynamics and Neurobehavioral Geometries in Psychiatric Illness

I study spatiotemporal patterns of brain dynamics and neuro-behavioral geometries in Schizophrenia, Addiction and PTSD.

Disruptions of Brain Networks in Neurological Disorders

I use simultaneous EEG-fMRI to study alterations in patterns of brain network integration and segregation in sleep deprived healthy adults and in patients with epilepsy.
