PhD, Brown University, 1978
MA, Georgetown University, 1975


After one year of full-time teaching at Rutgers University, I began working at the National Center for Health Statistics (NCHS), on the National Survey of Family Growth (NSFG), in 1978. I served as its project manager from 1992-2014.  I joined the JHU faculty in September 2014.   My interests include socioeconomic disparities and trends in fertility, contraceptive use, unintended pregnancy, marriage and divorce, and their health and socioeconomic consequences. My recent research has also included studying these topics for women with disabilities.   Given my experience in managing surveys, I am also interested in survey methods that will allow us to study these topics in a cost-effective way.
