Eric O. Freed, Ph.D.
Dr. Freed is recognized as a leader in the field of virus assembly who has made important strides in understanding the mechanisms of retroviral replication at the molecular level, with an emphasis on late stages of the HIV-1 replication cycle. As Director of the HIV DRP, he oversees a program of basic, translational, and clinical research aimed at developing a better understanding of HIV that can be used to generate more-effective treatment strategies. His research focuses on HIV-1 Gag trafficking, Env incorporation, virus assembly, budding, release, and maturation. Dr. Freed has a special interest in the complex relationship between viral proteins and cellular factors and pathways, believing that characterizing fundamental aspects of the retrovirus life cycle will suggest novel targets for the development of antiretroviral therapies.
