The growing societal burden of neurodegenerative disease as the average age of the world population increases, as well our inability to develop effective clinical treatments, poses a critical problem. Although many therapeutic factors can effectively treat animal models of Alzheimer's disease, progress has been slowed by the challenge of successfully delivering therapies to the aged human brain. My graduate work focused on the development of adeno-associated virus (AAV) vectors for gene delivery to the nervous system. As a postdoctoral fellow, I have applied my graduate training in the rational design and neurobiological function of AAV vectors to develop novel gene therapies for the treatment of AD. In transitioning to the field of aging research, I aim to harness my expertise with AAV vectors to enhance our ability to control and target therapeutic gene delivery to the aged brain.
