My research team studied viral pathogenesis with particular interest in influenza virus and respiratory syncytial virus (RSV) infections. Our particular interest was in the role of active infection of human mononuclear leukocytes by viruses during a developing antiviral response. My laboratory program was developed with support from NIAID (1979-2009) and, additionally in later years, the NATO Science for Peace Programme, until the laboratory was closed in 2009.

My studies, including results recently and currently being published, addressed: 1. The mechanisms whereby RSV causes recurrent clinical infection in individuals who have evidence of immunity to the virus. 2. The impact of HLA-associated determinants on influenza virus infection of leukocytes. The aims were to characterize the intrinsic resistance of lymphocytes with certain HLA haplotypes to infection by influenza virus. 3. The ability of gene segments from the highly pathogenic avian influenza (HPAI) H5N1 virus to reassort with segments from human H1N1 or H3N2 viruses to produce potential pandemic strains, and the activity of current and investigational antiviral agents to treat the parental and such potential reassortant strains. 4. The regulation of immune responses in the lung, such that constant inflammation in response to inhaled material is avoided or suppressed but an immune response to a pathogen such as influenza virus is initiated and recovery is assured.

I am the author or co-author of more than 95 articles in peer-reviewed journals, as well as textbook chapters and other publications. I currently serve as invited guest editor for several research journals related to virology and the immunology of infectious diseases, such as for a special issue on "Immunopathogenesis of Influenza Virus and Respiratory Syncytial Virus Infection."
