Dr. Carl June, Penn Medicine, has been named one of TIME Magazine’s 100 most influential people in the world. As a surprise to Dr. June, Emily Whitehead was asked to write a brief tribute for the 2018 TIME 100 issue.

Congratulations and THANK YOU, Dr. June, for your influence on the development of CAR-T cell therapy!
