Research Interest
Dr. Lee’s lab studies the genetic and molecular mechanisms underlying the effect of aging in human neurons. To understand how the aging of human neurons contributes to their vulnerability to neurodegeneration, Dr. Lee’s lab focuses on modeling the aging process with human neurons generated by a direct neuronal reprogramming (conversion) approach that can directly convert fibroblasts into neurons. Further, applying this conversion approach to longitudinally collected fibroblasts from the same individual, Dr. Lee’s lab investigates the key regulator of human neuronal aging in longitudinal modeling of all neuronal subtypes. Tissue culture systems of human fibroblasts and neurons are primarily used with genetic, molecular, and biochemical techniques to study human neuronal aging.
