Dr. Sarah Mulkey is a Prenatal-Neonatal Neurologist in the Zickler Family Prenatal Pediatrics Institute at Children’s National Hospital and a Professor of Neurology and Pediatrics at The George Washington University School of Medicine and Health Sciences in Washington, DC.
She is the Co-Director of the Congenital Infection Program and the Director of the Fetal Neurology Fellowship at Children’s National Hospital.
Dr. Mulkey’s research interests include brain injury in the fetus and newborn, congenital infectious encephalopathies including Zika virus, and evaluation of neurodevelopmental outcomes. She has contributed to national guidelines for the care of infants exposed to infection during pregnancy. Her research in this area focuses on neuroimaging and long-term neurodevelopment of infants exposed to congenital infections such as Zika virus, SARS-CoV-2, and Lyme disease.
Dr. Roberta DeBiasi is chief of the Division of Pediatric Infectious Diseases and the Co-Director of the Congenital Infection Program at Children’s National Hospital. She was recently named the Robert H. Parrott Professor of Pediatric Research at Children’s National and is a tenured Professor of Pediatrics and Microbiology, Immunology and Tropical Medicine at George Washington University.
In addition to her active involvement in clinical care, Dr. DeBiasi’s research career has been devoted to studying severe and congenital viral infections and emerging infectious diseases such as Ebola, Zika virus, SARS-CoV-2, MIS-C, and Lyme disease. She is the lead investigator at Children’s National Hospital for the Clinical Trials Network Coordinating Center for Lyme and other Tick-borne Diseases.
Meagan Williams is a Lead Clinical Research Coordinator at Children’s National Hospital. Her research interests involve supporting the well-being of children and families after adverse exposures, and she is dedicated to incorporating patient-centered, strengths-based, and trauma-sensitive principles into all stages of the research process.
In collaboration with Drs. Mulkey and DeBiasi, she has coordinated studies on child development and assessing the short- and long-term impacts of antenatal infectious exposures both domestically and internationally, including SARS-CoV-2, MIS-C, Zika virus, and Lyme disease.
Dr. David Schwartz is a medical epidemiologist and a board-certified pathologist. He is a globally recognized expert in obstetric, placental and perinatal pathology as well as infectious disease pathology. He has more than 45 years of experience investigating pregnancy complications and cause(s) of stillbirth, fetal injury and maternal death. He has investigated placental and perinatal pathology; how emerging and reemerging infectious diseases affect pregnant women, the fetus, placenta and newborn; mechanisms of microbial maternal-fetal transmission; and the effects of vaccination on pregnancy infections.
He has investigated new microbial agents including emerging and reemerging infectious diseases since the beginning of the AIDS pandemic, and has made significant contributions to understanding bacterial, parasitic and fungal diseases, HIV, Zika virus, Ebola virus and other hemorrhagic fevers, and most recently, mpox (monkeypox) and Lyme disease.

“I am thrilled to see that one of the leading national neurology experts on the impact of infection on birth outcomes, Dr. Sarah Mulkey, has designed this pivotal longitudinal study. We encourage all women who acquire Lyme disease during pregnancy to consider contacting Dr. Mulkey to discuss participation in this study.”
– Brian Fallon, MD, MPH, Director of the Lyme & Tick-borne Diseases Clinical Trials Network, Columbia University Irving Medical Center
