Carol Sanger is the Barbara Aronstein Black Professor of Law at Columbia Law School in New York, where she teaches courses on contracts, family law, and others focusing on reproduction, the legal profession, and law and gender. Her most recent work is About Abortion: Terminating Pregnancy in the 21st Century, and looks at the regulation of abortion, the regulation of maternal conduct, surrogacy, and what the connection is between these laws and current US culture, including new laws the force women wanting abortions to have ultrasounds, which Sanger calls "exploiting the emotional power of fetal imagery".
