— Erica Ollmann Saphire, Ph.D. // Professor

Overview

Erica Ollmann Saphire, Ph.D. is a Professor of the La Jolla Institute for Immunology. Her research explains, at the molecular level, how and why viruses like Ebola and Lassa are pathogenic and provides the roadmap for medical defense. Her team has solved the structures of the Ebola, Sudan, Marburg, Bundibugyo and Lassa virus glycoproteins, explained how they remodel these structures as they drive themselves into cells, how their proteins suppress immune function and where human antibodies can defeat these viruses.

A recent discovery revealed why neutralizing antibodies had been so difficult to elicit against Lassa virus, and provided not only the templates for the needed vaccine, but the molecule itself: a Lassa surface glycoprotein engineered to remain in the right conformation to inspire the needed antibody response. This molecule is the basis for international vaccine efforts against Lassa.

Dr. Saphire was also the galvanizing force behind the Viral Hemorrhagic Fever Immunotherapeutic Consortium and is the Director of this organization. This consortium, an NIH-funded Center of Excellence in Translational Research, unites 44 previously competing academic, industrial and government labs across five continents to understand and provide antibody therapeutics against Ebola, Marburg, Lassa and other viruses.

Dr. Saphire’s work has been recognized at the White House with the Presidential Early Career Award in Science and Engineering, with young investigator awards from the International Congress of Antiviral Research, the American Society for Microbiology, and the MRC Centre for Virus Research in the United Kingdom. She has been awarded a Fulbright Global Scholar fellowship from the United States Department of State and a Mercator Fellowship from Deutsche Forschungsgemeinschaft, to develop international collaborations using cryoelectron microscopy to further global health.
