Yvette Sheline, MD, M.S.

McLure Professor of Psychiatry, Radiology, and Neurology

Director, Center for Neuromodulation in Depression and Stress

Director, Section on 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: using an accelerated iTBS protocol to treat depression and bipolar disorder; neuromodulation using cloud-based real-time fMRI; the neural predictors of outcome to computerized cognitive behavioral therapy (CCBT); and 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

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.

Walid Makhoul, MD

Walid Makhoul, MD

Research Specialist C

Walid has completed his NIH T32 fellowship in affective disorders here at the CNDS. He is leading both our Bipolar clinical trial and our treatment-resistant depression study using iTBS. 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.
