PMC Clark Scholar Dr. Nicole R. Nissim is a post-doctoral fellow at the University of Pennsylvania (LCNS, Department of Neurology) and Moss Rehabilitation Research Institute through the NIH T32 fellowship program in translational neuroscience and neurorehabilitation research. Dr. Nissim received her PhD in biomedical sciences with a concentration in neuroscience from the University of Florida in 2019. Her research explored cognitive aging and the impact of transcranial direct current stimulation (tDCS) on functional connectivity of the working memory network in healthy older adults. Dr. Nissim’s post-doctoral research involves understanding the effects of transcranial alternating current stimulation (tACS) on neurophysiological markers underlying cognition and aims to develop interventions involving tACS in populations with mild cognitive impairment or neurodegenerative disease. Her research interests include understanding the impact of non-invasive brain stimulation on brain function and network level connectivity to facilitate recovery of cognitive impairments (e.g. working memory, language, executive function) after brain disease or injury.
