SciVal Experts Research Profile

Research and Professional Experience

Mr. Laeyendecker manages Dr. Thomas Quinn’s International HIV Laboratory. He has worked at Johns Hopkins University on infectious diseases projects for the last 20 years.

The strategic mission of the International HIV Laboratory is to investigate the viral kinetics of HIV in defined populations with emphasis on transmission, pathogenesis, gender and impact of antiviral drugs. The laboratory’s mission is pursued by leveraging our strategic alliances and access to cutting edge molecular tools to test well characterized epidemiologically linked samples. Mr. Laeyendecker currently directs research projects investigating the effect of HIV viral subtypes on disease progression, the selection of viral variants during sexual and parenteral transmission of HIV, the world-wide diversity of HSV-2 serologic response, and the optimization of cross sectional HIV incidence testing. An additional focus is the development and implementation of low cost testing methodology for diagnosis and monitoring of HIV and other infectious diseases in developing countries.

In addition to research projects Mr. 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.
