Scientific Interests

Dr. Marta Epeldegui's research for several years has focused on better elucidating the immunopathogenesis of HIV/AIDS, especially that of AIDS-associated lymphoma. Her Ph.D. focused on the role of activation-induced cytidine deaminase (AID) in driving oncogenic molecular changes in B cells, and on the induction of B cell activation by HIV virions, defining the role of CD40 ligand in this process. Currently, she is studying the association of immune activation in the development of HIV infection-associated lymphoma.
