Dr. Rebecca Gottesman, M.D., Ph.D.


Dr. Rebecca Gottesman received her medical degree from the Columbia College of Physicians and Surgeons in New York. She completed her internship in internal medicine at The Johns Hopkins Bayview Medical Center and her neurology residency at Johns Hopkins Hospital in Baltimore, Maryland. After her residency, she received a Ph.D. in the Graduate Training Program in Clinical Investigation (GTPCI) from the Johns Hopkins Bloomberg School of Public Health.


Dr. Gottesman is currently an Associate Professor of Neurology and Epidemiology at Johns Hopkins, with particular interest in cerebrovascular neurology and clinical research in stroke. She is interested in the short- and long-term cognitive effects of vascular disease and stroke, and uses a combination of clinical studies in patients with stroke or other vascular disease as well as epidemiological studies to evaluate the impact of vascular disease on the brain. She works in particular with the Atherosclerosis Risk in Communities (ARIC) study.


Dr. Gottesman currently sees stroke patients at The Johns Hopkins Bayview Medical Center in Baltimore, Maryland on Wednesdays.

Dr. Mona Bahouth, M.D.


Originally from sunny Syracuse, New York, Dr. Mona Bahouth completed her undergraduate education at the University at Buffalo, Masters degree from Syracuse University, and Medical degree from the University of Maryland School of Medicine. Her previous clinical work has focused on establishing systems of care in acute stroke and clinical trial research to develop novel therapies/approaches to care. Her continued research interest focuses on the evaluation of current stroke practices and their impact on patient outcome.


Working with SCAN, she is currently investigating the correlation between dehydration and stroke outcome. She believes that with information gained through this research, we can design a prospective and randomized trial to prescribe more precise fluid resuscitation algorithms for the acute stroke patient.

Bridget Chen


Bridget Chen is currently an undergraduate junior at Johns Hopkins University studying for her Bachelor’s in Neuroscience with a cellular and molecular focus. In the past, she volunteered for several years at an inpatient rehabilitation unit where she observed and interacted with patients who were recovering from stroke. Because of this, she aspires to be a stroke neurologist and is particularly interested in the connection between the cerebrovascular risk factors that lead to stroke and developing Alzheimer’s Disease. Currently is she working on a research project that involves giving neuropsychological tests to examine cognition in heart failure patients before and after they get diuresis  treatment.

Originally from Germany, Dr Roland Faigle received a PhD in medical cell biology from the University of Gothenburg, Sweden, before completing his medical degree at Marburg University in Marburg, Germany. Thereafter, he came to Johns Hopkins and completed a medical internship on the Osler Medical Service at the Johns Hopkins Hospital. He then completed a neurology residency at Johns Hopkins, followed by a fellowship in Cerebrovascular Disease and Stroke, also at Johns Hopkins. Dr. Faigle is currently an Assistant Professor in the Cerebrovascular Division in the Department of Neurology at Johns Hopkins, and is currently pursuing a Master’s degree in Clinical Investigation (MHS) at the Johns Hopkins Bloomberg School of Public Health.


Dr Faigle’s research focuses on the association between white matter disease, impaired cerebral autoregulation during cardiopulmonary bypass surgery, and perioperative stroke. In addition, he is interested in developing prediction models of mortality and other clinical outcomes in stroke patients. In particular, he aims to understand how racial differences and determinants modulate risk factors of mortality and poor ourcome in patients with intracerebral hemorrhage and ischemic stroke patients receiving IV thrombolysis.

Rachel Krieger, B.S.


Rachel Krieger completed her bachelor’s degree in Neuroscience and Molecular Biology at the Johns Hopkins University, where she conducted research on glial cell biology. Her current research interests focus on socioeconomic and racial disparities in the treatment of stroke, and she is working with Dr. Roland Faigle to study the mechanisms underlying these issues.


She is currently enrolling patients in a study examining the impact of race as a variable on the communication dynamics between stroke patients and speech-language pathologists, as well as another study examining whether patients of different races tend to receive treatment from speech-language pathologists at different rates. While she is conducting these projects during a gap year, she hopes to go to medical school in the fall of 2019 and aspires to one day be a neurologist herself.
