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.

ANGIESZKA ZUBERER, PH.D. - ASSISTANT PROFESSOR
Agnieszka explores the cognitive and neural mechanisms that shape our attention and emotional engagement in the world. Agnieszka is fascinated by understanding what makes us more or less engaged than others and how these processes impact our well-being. Agnieszka’s particular interest lies in advancing closed-loop paradigms, where brain stimulation protocols are refined using real-time behavioral and pupilometric markers. With a focus on optimizing attention and affect regulation, Agnieszka aims to contribute to the ever-evolving research in cognitive psychiatry.

ATHENA STEIN, PH.D. - POSTDOCTORAL SCHOLAR
Athena received her PhD from the University of Queensland in Brisbane, Australia. During her PhD, she investigated the novel use of non-invasive neurostimulation to improve attention in children with acquired brain injury. In particular, she investigated personalised treatment targets using brain connectivity measured from source-reconstructed high-density electroencephalography (HD-EEG), and developed an at-home neurostimulation clinical trial to improve attention in this population. Athena is now interested in furthering understanding of personalised application of neurostimulation in psychiatric populations. Outside of research, she also has experience in commercialisation, as well as science communication in regional and rural Australian schools. In her spare time, she enjoys cooking, running, and spending time outdoors.

Skye is completing her doctoral internship at UNC School of Medicine on the Affective Science track. This internship is in fulfillment of her final year of training to earn her PhD in Clinical Psychology from Purdue University. Skye's program of research focuses on understanding how individuals manage their emotional experiences, with particular interest in why and how this management breaks down (e.g., emotion dysregulation) and how to best intervene on harmful processes that maintain impairment in mood, anxiety, and personality disorders using multimethod (e.g., laboratory, psychophysiological, and intensive longitudinal) data collection and analysis. As part of her work in the Frohlich Lab, she is conducting clinical assessments and brief psychotherapeutic interventions and training in neurostimulation techniques for anxiety and depressive disorders. Outside of internship responsibilities, she enjoys hiking, weightlifting, and reading.
