Dr. Maria Houtchens is a neurologist at the Brigham Multiple Sclerosis Center, and Associate Professor of Neurology at Harvard Medical School.  Her work has helped define the modern subspecialty of women’s neurology in multiple sclerosis and neuroimmunology, particularly around pregnancy and reproductive health. At the Brigham Multiple Sclerosis Center, she founded the Women’s Health Program in 2011, and led the PREG-MS prospective pregnancy registry, which linked more than ten New England MS centers to systematically study maternal, fetal, and long‑term child outcomes, generating some of the first large U.S. datasets on MS and pregnancy. Through influential reviews and original investigations on pregnancy management, reproductive health, and pregnancy outcomes in women with MS, she has provided practical frameworks for counseling, disease‑modifying therapy decisions, and peripartum care that are now widely used in clinical practice. In addition, by directing a women’s neurology fellowship and leading educational activities on MS treatment before, during, and after pregnancy, she has trained a generation of clinicians to integrate reproductive planning into MS care, firmly establishing women’s neurology as a core dimension of neuroimmunology rather than a niche interest. She is currently a co-director of Women’s Neurology Program and Women’s Neurology Fellowship at Mass General Brigham, as well as a Clinical Director of the Brigham MS Center.
