Emmanuel Oga is a researcher with expertise in substance use and infectious disease surveillance. Dr. Oga contributes to our work on the epidemiology of substance use, including the role of harm reduction in improving the lives of people who use drugs, disease outbreak management and public health surveillance. Dr. Oga’s work focuses on the epidemiological correlates of substance use, health outcomes in key populations, including the role of stigma and discrimination, and on disease prevention, detection and response. Stigma can negatively impact utilization of prevention and treatment services by marginalized groups such as sex workers, people who use drugs, and people living with HIV. Dr. Oga maintains an interest in the measurement of stigma to facilitate improvement in access to prevention and treatment services.
Dr. Oga provides expertise and technical assistance on disease outbreak prevention, detection and response and is involved in support capacity development for public health emergency management.
Dr. Oga’s research on HIV and other infectious diseases has involved studies on the intersection of infectious diseases and cancer. These research interests have involved various health outcomes and have employed various methods, including survey research, clinical trials, clinical research, and public health program implementation.
