Since 2014, Barbara Gunsenheimer-Bartmeyer has been the deputy head of the HIV and AIDS, STI and other blood-borne infectious diseases unit at the Robert Koch Institute (RKI) in Berlin, Germany. This is a public health body under the umbrella of the German Ministry of Health and its main goals are the identification, surveillance and prevention of communicable and non-communicable diseases and the provision of evidence-based research for political decision making. RKI HIV research projects are focused on specific populations, such as men who have sex with men, people who inject drugs, migrants and trans people, and the scale up of PrEP in Germany in cooperation with HIV doctors, medical stakeholders and communities. Since 2021, the RKI unit has been the WHO collaborating centre for viral hepatitis and HIV. The unit heads several scientific HIV projects, including WHO HIV desk reviews in the WHO Euro region (Uzbekistan, Ukraine, Azerbaijan, North Macedonia and Kyrgyzstan).
