We talk with Dr. Mark Painter, a postdoctoral fellow at the University of Pennsylvania Perelman School of Medicine, PA, who studies the role of T cells following respiratory virus infection or vaccination as well as in immune memory, cancer, aging and autoimmunity.

We talk with Dr. Bernadeta Dadonaite, a research associate at the Fred Hutchinson Cancer Center, WA, who studies interactions between the influenza attachment protein hemagglutinin and its newly identified receptor protein, MHC-II.

We talk with Dr. Julianna Han, a senior staff scientist at the Scripps Research institute, CA, who studies antibody-epitope interactions following human influenza virus infection and vaccination to inform the development of novel influenza immunogens and antibody therapeutics.

We talk with Dr. Daniel Malouli, an assistant professor at the Vaccine and Gene Therapy Institute at the Oregon Health and Science University, OR, who studies how virus-host interactions modulate CMV infection and pathogenesis as well as determine the safety and efficacy of CMV-based vaccine vectors.

We talk with Dr. Sumanta Naik, a staff scientist in the Department of Molecular Microbiology at Washington University School of Medicine, who is investigating the role of IRGM1 in type I interferon and B cell responses following vaccination and tuberculosis infection.

We talk with Dr. Mario Feldman, Professor of Microbiology at Washington University School of Medicine in St. Louis, MO who studies the pathogenesis of Acinetobacter and the biogenesis of bacterial extracellular vesicles.

We talk with Dr. Daniel Hoft, Director of the Division of Infectious Diseases, Allergy & Immunology and the Center for Vaccine Development at Saint Louis University School of Medicine in St. Louis, MO who studies the development of T-cell targeting vaccines against mucosally-invasive intracellular pathogens such as tuberculosis and influenza.

We talk with Dr. Michela Locci, Associate Professor of Microbiology at the University of Pennsylvania Perelman School of Medicine in Philadelphia, PA who studies how T follicular helper cells promote optimal germinal cell reactions and antibody responses following vaccination.
