Name Profile
S. Saif Hasan
Department of Biochemistry and Molecular Biology

The Hasan laboratory focuses on elucidating the structural basis of biological trafficking by membrane protein complexes and of the hijacking of these host complexes during assembly of epidemic causing virus such as SARS-CoV-2, Dengue virus, and pox viruses. We use state-of-the-art single particle cryoEM and X-ray crystallography to perform atomic-level investigations of how membrane proteins interact with their native ligands and with viral proteins. We hope to deduce fundamental details of dysfunction in membrane protein biology that underlies cancers, cardiac diseases, and neurodegeration. Our virus focused investigations will elucidate commonalities in how phylogenetically unrelated viruses exploit a few select host membrane proteins to achieve progeny propagation, an approach which could one day lead to the development of broad spectrum anti-virals.

Osnat Herzberg
Department of Chemistry and Biochemistry

Dr. Osnat Herzberg is a structural biologist interested in the relationship between the function and structure of proteins and how protein-ligand interactions can guide drug discovery. The Herzberg lab uses X-ray crystallography and other biophysical, biochemical, and cellular approaches to better understand various experimental systems.

Jeffrey Hudgens
Biomolecular Measurement Division

Dr. Jeffrey Hudgens investigates the precision of hydrogen-deuterium exchange mass spectrometry (HDX-MS) and its application to the measurement of protein-ligand and glycoprotein-ligand interactions, the dynamical structures of mAbs, lipid-protein complexes, and membrane protein interactions. In addition to these fundamental determinations of the relationship between biomolecular structure and function, Dr. Hudgens also invents new apparatus and methods that improve HDX-MS methodology, especially as related to biopharmaceutical analysis. These improvements and insights will enable HDX-MS to be used in comparability studies of innovator and biosimilar drugs, thus advancing biopharmaceutical development and regulation.
