Dr. Hiromi Sesaki is a Professor in the Department of Cell Biology at Johns Hopkins University School of Medicine. His research focuses on mitochondrial dynamics—specifically the processes of fusion, fission, and mitophagy—and their roles in cellular health and aging. Through his work, Dr. Sesaki aims to understand how these mitochondrial behaviors influence neurodegenerative diseases, including Parkinson’s and Alzheimer’s, and to develop potential therapeutic strategies to enhance mitochondrial quality control mechanisms.
