FLAVIO FROHLICH, PH.D. – PRINCIPAL INVESTIGATOR

Flavio’s goal is to revolutionize how we treat psychiatric illnesses. His vision is that understanding cortical state dynamics will enable the development of novel non-invasive brain stimulation paradigms that directly target pathological network dynamics. Flavio is convinced that such rational design of neurotherapeutics will open the door for individualized, highly effective brain stimulation in psychiatry. Flavio directs the Carolina Center for Neurostimulation that offers numerous clinical trials of novel experimental treatments for depression and other mental illnesses.

Postdoctoral & Associated Scholars

JUSTIN RIDDLE, PH.D. - POSTDOCTORAL SCHOLAR & STUDY DIRECTOR

Justin Riddle graduated with a Ph.D. in Psychology from the University of California, Berkeley. He is studying the mechanistic role of neural oscillations in cognition. He uses noninvasive brain stimulation concurrent with neuroimaging to analyze the network level organization of the brain as human subjects engage in cognitive control. Justin is the Scientific Director of the Carolina Center for Neurostimulation. Justin hopes that his research will provide crucial scientific groundwork for the development of new brain stimulation treatments in psychiatry. In his free time, Justin is an avid yoga practitioner, board gamer, and consciousness enthusiast.

SUSANNE RADTKE-SCHULLER, PH.D. - ASSOCIATE RESEARCH SCIENTIST

Susanne focuses on the question how neuroanatomical structure is linked to neurophysiological function and especially what is the 'hardware' underlying behavior and cognitive processing in the brain. She is convinced that this is essential to understand brain processes in healthy and pathological states.

TOBIAS SCHWIPPEL, M.D. - POSTDOCTORAL SCHOLAR & STUDY DIRECTOR

Tobias received his medical doctor from the University of Tübingen, Germany. During his Psychiatry Residency in Tübingen, Tobias combined his clinical work with research and participated in brain stimulation studies in patients with alcohol use disorder, depression and schizophrenia. After board certification as psychiatrist and psychotherapist, Tobias moved to UNC to fully concentrate on neurophysiological research. He aims to investigate the relation between transdiagnostic symptoms and neural oscillations by means of non-invasive brain stimulation. His goal is the extension and combination of existing treatment tools for mental disorders. Tobias is the Director of Clinical Research at the Carolina Center for Neurostimulation. Outside of work, Tobias enjoys literature, political discussions and is joyfully struggling with yet another ball to juggle: his lack of rhythm in guitar playing and the perfect boardgame move.

MENGSEN ZHANG, PH. D. - POSTDOCTORAL SCHOLAR

Mengsen Zhang earned her Ph.D. in Complex Systems and Brain Sciences from Florida Atlantic University and was trained as a postdoc at Stanford University in computational neuroscience. She works to unravel the mystery of complex systems – how complex function and organization of the brain and social systems emerge out of simple (but no simpler) interaction between the constituents. She is currently developing computational techniques for analyzing and modeling oscillatory brain dynamics across multiple spatiotemporal scales, bridging animal and human research.
