Expertise: AIDS, HIV, Virology, Infectious Diseases

Wu, assistant professor in the College of Science’s Molecular and Microbiology Department, has spent the last six years decoding the molecular processes of the AIDS virus. AIDS, a devastating disease that is caused by the human immunodeficiency virus (HIV), affected more than 33 million people worldwide in 2007, according to World Health Organization statistics. A widely published researcher whose work has appeared in prestigious scientific journals such as Science, Journal of Virology, Virology, Retrovirology and Current HIV Research, Wu believes that a solution to the AIDS epidemic is possible. The 2009 NYCDC AIDS Ride (, which takes place in September, will support the next stage of Dr. Wu's research which has the potential to stop the HIV virus from becoming AIDS. Wu earned a doctorate in virology in 1998 from Queens University in Kingston, Ontario, Canada, after spending four years studying the DNA replication of the baculovirus family — a group of viruses that are fatal to insects and are often used for nonchemical pest control. He subsequently served for four years as a research fellow at the National Institutes of Health (NIH) where he began examining HIV infection in humans prior to joining Mason’s faculty in 2003. Wu has been the recipient of many awards and honors including the 2007 "Tomorrow's PIs" by Genome Technology Magazine, the 2006 Siemens Mentor Award by the Siemens Foundation, and the 2003 NIH Fellows Award for Research Excellence by NIH.
