Carolyn L. Westhoff

Professor of Epidemiology & Population and Family Health at the New York Presbyterian Hospital & at the Columbia University Medical Center

Professor of Obstetrics and Gynecology at the New York Presbyterian Hospital & at the Columbia University Medical Center, College of Physicians and Surgeons (Home Department)

Dr. Westhoff's work focuses on improving access to and quality of contraceptive and abortion services through education and research. She has published over 170 scientific articles, as well as many abstracts, relating to safety and effectiveness of contraception and abortion. Current clinical trials evaluate new approaches to contraception such as the use of microbicidal agents that can protect against HIV as well as against pregnancy. In addition, trials evaluate new and simpler ways to initiate contraceptive methods, and evaluate whether drug interactions interfere with contraceptive efficacy. Numerous recent studies have evaluated the safety and effectiveness of early abortion using medications rather than procedures. All studies and projects welcome the involvement of public health students as well as clinicians.

Dr. Westhoff serves as editor-in-chief of the international health journal, Contraception, a monthly publication for the advancement of reproductive health. The journal, published by Elsevier, is the official journal of the Society of Family Planning and the Association of Reproductive Health Professionals
