Career
Dybul started his career by working with AIDS patients in San Francisco, California. Under the presidency of George W. Bush, he was appointed as the United States Global AIDS Coordinator, leading the implementation of the President's Emergency Plan for AIDS Relief from 2006 to 2009. However, he is a registered Independent. He is the first out gay ambassador with the rank of Assistant Secretary of State.

Dybul was asked to stay on temporarily during the Barack Obama presidency transition, but was required to resign following the administration change, as he was a political appointee of the Bush administration. On November 15, 2012, he was appointed the next executive director of the Global Fund to Fight AIDS, Tuberculosis and Malaria. His selection as executive director by the Global Fund's board during its 28th meeting in Geneva was met with praise from both donors and the development community. World Bank President Jim Yong Kim called Dybul's appointment a "superb choice for a crucial role". In an interview published in the Global Fund's digital newsletter, Dybul said his role as the Global Fund's new head "will be to maintain the strong forward trajectory of the Fund in order to end the three diseases". He assumed his role of head of the Global Fund in February 2013.

Dybul is a professor in the department of medicine at the Medical Center of Georgetown University and the codirector of the Center for Global Health Practice and Impact. He is a member of the Global Health Initiative faculty committee. From 2020 until 2022, Dybul served as a member of the Independent Panel for Pandemic Preparedness and Response, a group examining how the World Health Organization and countries handled the COVID-19 pandemic, co-chaired by Helen Clark and Ellen Johnson Sirleaf. In the preparations for the Global Health Summit hosted by the European Commission and the G20 in May 2021, he was a member of the event's High Level Scientific Panel.

Dybul has been an executive vice-chairman of Enochian Biosciences, a US biotechnology company, since 2019, before being appointed as its CEO in 2021.
