Our Research

Our team leads several research programs funded largely through federal agencies to study origin, health effects and development process of diseases, and to develop new ways to diagnose and treat them. Our research areas include:

  • Programs in India, Uganda and Columbia funded in part by the National Institutes of Health and the Gates Foundation to determine the impact of HIV infection on the neurological health of the infected populations.
  • Clinical, pathological and molecular studies to characterize the effects of various clades of HIV infection on the brain and peripheral nervous system.
  • NIH-funded programs in Puerto Rico and Hawaii to study the effect of HIV infection in women and in the elderly populations.

About Richard T. Johnson

Richard T. Johnson was an internationally renowned Johns Hopkins neurologist who is credited with inventing the field of neurovirology—the study of viruses that infect the nervous system. A member of the Johns Hopkins University School of Medicine faculty from 1969 to 1997, Johnson served as director of the Department of Neurology from 1988 until 1997 and also had a joint appointment in the Department of Immunology and Infectious Diseases in JHU's Bloomberg School of Public Health. He mentored more than 55 postdoctoral fellows in virology, neurology, immunology, and neurovirology, with at least 10 of them going on to become heads of their own departments.
