Dr. Stark's research projects include improving maternal and child health, nutrition, and health disparities in the African countries of Burkina Faso, South Sudan, Rwanda, and Ethiopia. Dr. Stark teaches courses at the undergraduate and graduate level in the College of Public Health and Health Professions, on global health, epidemiology, nutrition and clinical diagnosis.
Dr. McKune’s research investigates the complex, human and natural system dynamics – including hygiene, livestock ownership, climate, and social determinants - that affect human health outcomes. Though her work often focuses on child growth and nutritional outcomes in sub-Saharan Africa, she has contributed to understanding of HIV/AIDS, maternal health outcomes, Ebola, and, most recently, COVID-19.
Dr. Acosta's research includes projects related to climate change and health, nutrition, food security, vaccine supply chains, vaccine value chains, and mental health. He is a mixed-methods researcher with experience in both quantitative and qualitative data collection and analysis in complex environments, such as Senegal, Mauritania, and the Karamoja subregion of Uganda. Dr. Acosta teaches several courses at PHHP about global health, public health, environmental health, and one health.
