Growing up, Moses Kim, M.D., Ph.D., was certain he would one day become a scientist. As a child, he moved with his family from Korea to San Francisco, bringing with him a fascination for what he calls “hardcore science.” At University of California, Berkeley, Dr. Kim studied the complex world of molecular biology as he pursued a combined M.D./Ph.D. program. Later at University of California, San Francisco, he conducted research in the lab of Elizabeth Blackburn, who won the Nobel Prize for the discovery of telomeres.
