Dr. Thomas F. McElrath, M.D., Ph.D.

Massachusetts, USA

Medical Advisory Board Member

Dr. McElrath serves two roles regarding his practice in obstetrics and women’s health: The first is as a clinician specializing in Maternal-Fetal Medicine with a particular interest in maternal health, and the second is as a researcher seeing solutions to the prediction and treatment of complications in pregnancy.

As a physician, Dr. McElrath is a leader in the management of pregnancies that are at high risk of preterm delivery, preeclampsia, and other hypertensive disorders of pregnancy. He is the Medical Director of the Preterm Birth Clinic at the Brigham & Women’s Hospital in Boston. The clinic specializes in a variety of contemporary techniques to prevent preterm/recurrent preterm delivery, including abdominal cerclage. At the same time, he runs several clinics specializing in the treatment of chronic medical conditions in pregnancy, including the nation’s first Neurology in Pregnancy Clinic specializing in treating patients with chronic neurological disorders, particularly epilepsy and multiple sclerosis. Dr. McElrath is also highly experienced in the management of Crohn’s Disease and Ulcerative Colitis during pregnancy and has a more recent sub specialized interest in the management of Cystic Fibrosis in pregnancy.

As a researcher, Dr. McElrath is the founder and Principal Investigator of the LIFECODES Birth Cohort. This is one of the largest birth cohorts in North America and is run out of the Brigham & Women’s Hospital. Dr. McElrath’s research group specializes in two separate areas of pregnancy epidemiology: The first is in the use of machine learning in the development of molecular biomarkers that signal a patient’s risk of impending pregnancy complications including preeclampsia. The second is in the investigation of environmental endocrine disrupting exposures that increase a patient’s risk of preeclampsia or preterm birth.

The LIFECODES cohort has been recruiting since 2006 and enrolls approximately eight patients per week.
