Florian Krammer

Florian Krammer, Ph.D.

Dr. Krammer is an Associate Professor in the Department of Microbiology at The Icahn School of Medicine at Mount Sinai Hospital. The Krammer laboratory studies cross-reactive antibody responses to the surface glycoproteins of antigenically variable RNA viruses. His main focus is in influenza viruses with a special focus on antibody responses to hantaviruses, filoviruses, and other emerging RNA viruses. Work done in the laboratory includes the expression and characterization of viral glycoproteins, generation of glycoprotein-directed monoclonal antibodies, and the characterization of the interaction between antibodies and surface glycoproteins; his lab as specific interest in analyzing conserved epitopes and – through detailed studies – aim to elucidate the mechanisms by which these antibodies protect the host from viral infection and disease. The final goal is to translate these findings into novel vaccines and therapeutics. (PC: Sebastian Krammer)
