Dr. Louis is the Department Chair for the Department of OB/GYN at University of South Florida. She is a specialist in Maternal Fetal Medicine and serves as the Immediate Past President for the Society for Maternal Fetal Medicine. Dr. Louis has a joint faculty appointment in both the College of Public Health and the College of Medicine at USF. Her research in obstructive sleep apnea in pregnant women led to a career focused on maternal morbidity and mortality. After completing a Maternal Fetal Medicine fellowship at Wayne State University/NIH Perinatology Research Branch, Dr. Louis embarked on a career studying obstructive sleep apnea in pregnancy. At the time, little was known about the disease and its implications for maternal and infant health. She collaborated with sleep medicine experts and anesthesiologists to define the outcomes associated with sleep apnea in pregnancy. Her research portfolio has expanded to include research on maternal morbidity and mortality and cardiometabolic consequences of sleep disorders. She has authored more than 70 scientific articles and book chapters. NIH, Robert Wood Johnson Foundation, foundations and industry, have funded her research. Dr. Louis has focused her most recent advocacy work in research and has been a champion of studying health inequity and inclusion of pregnant people in clinical trials. She continues to be passionate about mentoring students and trainees with the belief that research is an essential part of medical education.
