Jon is a senior public health scientist in the Behavioral Health Research Division at RTI International, where he conducts behavioral epidemiological research on risk factors and health outcomes associated with the illicit drug use and drug injection. He is a medical anthropologist by training with two decades of community-based, epidemiological field experience in the areas of parenteral infectious disease, drug overdose, and drug user health. Before coming to RTI, Dr. Zibbell worked as a Centers for Disease Control and Prevention (CDC) health scientist in the Divisions of Viral Hepatitis and Unintentional Injury Prevention conducting epidemiological and surveillance research while assisting states during outbreak investigations to respond to injuries and infections caused by drug use behaviors. He has been awarded numerous CDC Director’s Awards for domestic outbreak response, including HIV and opioid overdose outbreak investigations as lead qualitative researcher. Dr. Zibbell was a member of President Obama’s White House Heroin Task Force where he helped developed the Administration’s response to the illicit opioid epidemic, and he was appointed to CDC’s syringe services program steering committee to help develop HHS guidelines for the federal government’s support of needle exchange. Beyond research, Dr. Zibbell has conducted rapid ethnographic needs assessments for community-based harm reduction programs and continues to assist states and community organizations in developing evidence-based approaches to reduce morbidity and mortality associated with illicit drug use and related sequela. His work has appeared in both academic and professional journals and he currently holds a joint, adjunct appointment in the Center for the Study of Human Health and the Department of Anthropology at Emory University.
