Assistant Professor School of Sciences

Our group is mainly focused on the RNA regulation of B cell biology. We found that disruption of specific RNA processing and modification pathways would impair B cell development and humoral immune responses. We are trying to identify the RNA substrates and figure out how these pathways are linked to modulating B cell development and differentiation.
