PI Viewpoint by Pamela J. Bjorkman: I stand with the Association of American Universities to urge a permanent end to executive or other orders barring the entry or return to the US of individual from certain countries and to ensure a visa policy that welcomes the most talented individuals from all parts of the world to study, teach, and carry out research in our country.

Our laboratory is interested in immune recognition of viral pathogens. We are particularly interested in understanding the immune response against HIV-1 and influenza in order to develop improved therapeutics. We use X-ray crystallography, electron microscopy, and biochemistry to study pathogen envelope glycoproteins and host immune response proteins. Using structural information and alternate antibody architectures, we are engineering antibody-based reagents with increased potency and breadth. We are also investigating the structural correlates of broad and potent antibody-mediated neutralization of HIV-1 to better understand what leads to naturally-occurring broad and potent antibodies. In related work, we use 3D imaging techniques such as electron tomography and fluorescent microscopy to investigate HIV/SIV infection in animal and human tissues.
