Dr. Laeyendecker is a scientist and administrator.  He manages Dr. Thomas Quinn’s International HIV Laboratory. He has worked at Johns Hopkins University on infectious diseases projects for more than 20 years.

The strategic mission of the International HIV Laboratory is to investigate:  (1) develop methods for epidemiologic investigation of HIV, HCV and HSV-2 with an emphasis on being able to estimate incidence from cross-sectional surveys; (2) examine  epidemiologic, clinical, virologic, and immunologic features of HIV infection in the United States and in developing countries; (3) examines the viral kinetics and other biological and behavioral factors associated with HIV transmission; (4) characterizes the molecular strains of HIV by region for differences in pathogenesis, infectiousness, transmission, and immunologic response; (5) develops and evaluates novel interventions to prevent HIV transmission, including microbicides, circumcision and vaccines; (6) examines the efficacy of antiretroviral drugs in preventing transmission and increasing survival in developing countries.

In addition to research projects Dr. Laeyendecker is involved in the development and support of laboratory projects in Uganda. These include the Intramural Center for Excellence in Research (ICER) laboratory facility in Kalisizo, Uganda, at the Rakai Health Sciences Project, and the Infectious Diseases Institute in Kampala Uganda.
