Associate Research Scientist
Chaim Schramm is an associate research scientist in the Honig and Shapiro labs. In his research he uses deep sequencing of peripheral B cells to investigate the development of rare antibodies capable of neutralizing most strains of HIV and and to study the nature of the immune response to chronic infection. This information will be useful for designing targeted immunogens that could serve as the basis for a protective vaccine.
Chaim earned his PhD at the University of Pennsylvania, where he studied the structural biology of membrane proteins, focusing on the effects of primary sequence on structural interactions.
