Yvette Sheline, MD, M.S.

McLure Professor of Psychiatry, Radiology and Neurology Director, Center for Neuromodulation in Depression and Stress Directoy, Section Mood, Anxiety and Trauma

Dr Sheline is the McLure Professor of Psychiatry, Radiology, and Neurology and Director of the Center for Neuromodulation in Depression and Stress (CNDS) at the University of Pennsylvania. Dr. Sheline has over two decades of experience conducting innovative clinical neuroscience research that bridges the fields of neuroimaging, translational research, and clinical treatment. Recent projects include: how the co-occurrence of particular symptoms, neuropsychological variables and structural and fMRI brain network measures may provide biotypes that cut across‘anxious-misery’disorders; the neural predictors of outcome to computerized cognitive behavioral therapy (CBT); neuromodulation using cloud-based real-time fMRI; and using an accelerated TMS protocol to treat depression

Desmond Oathes, PhD

Desmond Oathes, PhD

Associate Director CNDS and Co-Director brainSTIM Center, Assistant Professor of Psychiatry

Dr. Oathes is a licensed Clinical Psychologist and Assistant Professor in the Department of Psychiatry at the University of Pennsylvania. He specializes in interleaved TMS/fMRI to probe neural circuits and to generate novel neurotherapeutic targets. He also runs clinical trials for depression and PTSD and collaborates on TMS/behavioral studies on working memory, social cognition and other topics.

Nicholas Balderston, PhD

Nicholas Balderston, PhD

Research Assistant Professor of Psychiatry

Dr. Balderston has a 15-year background in experimental psychology, psychophysiology, neuroimaging, and neuromodulation. His work features TMS/TBS administration, TMS targeting/e-field modelling, resting state fMRI, working memory performance, working memory-related BOLD activity. He has developed and published on several cognitive paradigms, investigating the relationship between negative affect and cognition, behavior, psychophysiology, fMRI, magnetoencephalography, and most recently with causal manipulations like TMS. As an experimental psychologist with extensive methods experience, he aims to make a unique and impactful contribution to the research program of the department, both through his independent basic-science research program, and through a team science approach aimed at translating his findings to better treat the patient populations served by the department.

Post-Doctoral Fellows

Justin Reber

Justin Reber

Post-Doctoral Researcher

Justin received his PhD in Psychology and completed a 2-year postdoctoral fellowship at the University of Iowa before joining Dr. Oathes' lab in 2021. His doctoral and early postdoctoral work focused on investigating how focal lesions to different brain structures and networks affect various cognitive abilities and social behaviors. His previous research examined the outcomes of brain damage on domains ranging from valuation and working memory to empathy and psychopathic personality traits. As a member of the Oathes Lab, Justin hopes to learn how to use TMS and fMRI to modulate targeted brain networks and explore how neuromodulation can affect cognition and behavior.


Maria Prociuk

Maria Prociuk

Research Administrative Coordinator

Maria works with Dr. Sheline and others to ensure the center runs smoothly. In addition to her administrative duties such as scheduling, shipping, ordering, and organizing, she also assists in multiple research studies. Maria assists in grant submissions, IRB submissions and manuscript and abstract submission. Maria’s research duties include but are not limited to working with study sponsors, phone screens, speaking with participants and collaborators, assisting with participant visits and recruitment. Maria also supervises and closely works with our volunteers.

Romain Duprat, PhD

Romain Duprat, PhD

Clinical Specialist

Romain examines innovative TMS targeting methods taking into account individual variability. Ultimately, his goal is to better understand the factors involved in rTMS clinical response to optimize treatment protocols in depressive and anxiety disorders. To do so, he is using different tools, from behavioral testing to interleaved TMS/fMRI. Romain received his PhD in Medicine and Health Sciences from Gent University, Belgium. During his doctoral studies, he focused on the use of neuromodulation techniques to treat major depressive disorders. More specifically, he developed and tested a new stimulation protocol (accelerated iTBS) in treatment-resistant depressed patients. Romain also investigated the role of the reward system and anhedonia in the response to stimulation in the healthy and depressed state, at the behavioral and neuroimaging level (fMRI). Thanks to many collaborations and to his background in Molecular and Cellular Biology, Romain acquired a translational knowledge of rTMS neuromechanisms of action in the human brain and in animal models.

Walid Makhoul, MD

Clinical Research Coordinator B

Walid has completed his NIH T2 fellowship in affective disorders here at the CNDS. He is leading both our Bipolar clinical trial and our RECOVER (Vagal Nerve Stimulation). Walid has helped conduct TMS studies which study the effects of repetitive transcranial magnetic stimulation on neural activity and connectivity using TMS/fMRI as well as how the addition of a cognitive task organizes and augments this response to induce plasticity.
