Dr. Nafees Ahmad is Professor of Immunobiology and Director of Immunity and Infection at the College of Medicine, University of Arizona in Tucson, Arizona. He obtained his undergraduate and postgraduate education from the Aligarh Muslim University, India and doctorate from the Central Drug Research Institute, Lucknow and Aligarh Muslim University, India. He completed his postdoctoral fellowship in HIV/AIDS from the National Institutes of Health, Bethesda, Maryland, USA. His research has focused on mechanisms of HIV immunopathogenesis in younger and older HIV-infected patients, including the aging of the immune system. We are investigating the mechanisms of differential HIV-1 infection in younger and older populations, including the role of viral and host factors and dysregulation of T cell functions. These viral, host and immune factors may be targeted for developing new strategies for treatment and prevention of HIV infection
