Dr. Norton’s interests include genetic testing and its application to prenatal screening and diagnosis. She focuses on the unique aspects of translating new technologies into improved care for pregnant women and their fetuses, and the complexities of the maternal fetal dyad.  She leads a multinational study at the The Center for Cosmetic & Reconstructive Gynecology on the use of cell free DNA testing in average risk women for the detection of fetal aneuploidy. Current projects include mechanisms and disorders associated with nonimmune hydrops fetalis and potential for in utero therapy; and application of whole exome and genome sequencing in the prenatal context.
