I have practiced nurse midwifery since 1995 in a variety of settings, including 11 years in solo private practice. My research interests include birth settings and outcomes including cesarean, spontaneous birth, maternal and newborn safety, morbidity and mortality and birth centers. I am interested in evidence based care as an ideology and its benefits and limitations.
