Abigail Greenleaf, PhD, is a public health demographer whose research focuses on collecting data in low- and middle-income countries. Abba is interested in survey research methods across a variety of public health topics. Her dissertation research assessed sources of error in cell-phone based estimates of modern contraceptive use among women in Burkina Faso. Abba currently works for ICAP's Population-Based HIV Impact Assessment (PHIA) survey. Carried out under the leadership of the Ministries of Health, PHIA data benchmark a country's progress towards controlling the AIDS epidemic and inform targeted policies and programs. Abba previously worked for the Centers for Disease Control as an Allan Rosenfield Global Health Fellow in Ethiopia and Cameroon. She is a Returned Peace Corps Volunteer (Cameroon 2007-2009).
