​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 is passionate about combining different methodological approaches to scientific problems and hopes to establish the field of network neuroscience. Flavio's personal website is here and he maintains tacs.academy, an online resource about tACS. When Flavio is not busy in the lab (ever?), he enjoys spending time with his family.

Postdoctoral & Associated Scholars

QI FANG, PH.D - POSTDOCTORAL SCHOLAR

Qi Fang obtained his Ph.D. in Neuroscience from the University of Southern California, where he mostly worked on the contextual and multimodal modulation of sensory processing and behavior via the mouse pulvinar. He now aims to further elucidate how pulvinar contributes to cognitive function via the posterior network oscillations using projection-specific experimental methods, and finally to translate the findings from animal study to the precise modulation of brain oscillation for treating patients with mental and brain disorders. He is also a big fan of deep learning and all state-of-the-art computational tools. Beyond science, Qi is a gourmet and enjoys traveling, hiking and classical music.

​RACHEL FORCE - POSTDOCTORAL SCHOLAR

​Rachel dedicated her career to furthering our understanding of the brain mechanisms involved in the experience of mental illness. With a PhD in the Biology of Psychopathology from the University of Minnesota and 20 years of experience in clinical research Rachel is excited about furthering the development of novel non-invasive brain stimulation methods to reduce symptomology and expand our understanding of how brain oscillation patterns may indicate risk for future pathology. Rachel is the Director of Clinical Research for the Carolina Center and also enjoys mentoring undergraduate research assistants. Outside of work, Rachel keeps her brain challenged raising two elementary aged kids, trail-running, and learning how to contra-dance.

ANITA FROHLICH, LL.M. - PROJECT MANAGER & SCHOLAR
​Anita loves to plan and organize. She (mostly) manages to convert her husband’s passions and the kids’ energy into a reasonably structured routine. As a homeschooling mom, Anita knows how to see things through from the beginning to the end. And her background as a comparative lawyer helps Anita to build bridges and find creative solutions to apparently unsurmountable obstacles. Anita’s wish is to help the Frohlich lab achieve its goal by optimizing the use of time and resources. In addition, Anita is on a journey to understand the neuroscience of conflict transformation in the context of psychiatric illnesses; she is a human translational and social neuroscience researcher in training. In her “free time” (an oxymoron for a mother of four kids!), Anita likes to play the cello and spend time in the garden.

JUSTIN RIDDLE, PH.D. - POSTDOCTORAL SCHOLAR

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.

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.

MENGSEN ZHANG, PH. D - POSTDOCTORAL SCHOLAR

Picture
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.
