Harvard presented six honorary degrees during the 2023 Commencement ceremony in Tercentenary Theatre.

Jennifer A. Doudna

Doctor of Science

Jennifer Doudna has dedicated her career to understanding the molecular structure of RNA and thereby improving the human condition. With Emmanuelle Charpentier, she received the 2020 Nobel Prize in chemistry for pioneering work on CRISPR-Cas9, a high-precision technology that enables targeted changes to the genome, with widespread applications across biology and medicine. Raised in Hawaii, she received her B.A. from Pomona College and her Ph.D. from Harvard. She served on the Yale faculty until 2002, when she moved to the University of California, Berkeley, where she is the Li Ka Shing Chancellor’s Professor of Biomedical and Health Sciences; professor of biochemistry, biophysics, and structural biology; and a Howard Hughes Medical Institute Investigator. She is a founder of the Innovative Genomics Institute, which deploys genome engineering to address problems in health, climate, and agriculture. Her many honors include the Breakthrough Prize in Life Sciences, the Gruber Genetics Prize, the Canada Gairdner International Award, the Japan Prize, the Kavli Prize in Nanoscience, and the Wolf Prize in Medicine. She is co-author of “A Crack in Creation,” a personal account of her research and the social and ethical implications of gene editing.

Thomas Jeffrey Hanks

Doctor of Arts

Tom Hanks is a renowned actor, producer, writer, director, and humanitarian, affectionately known as “America’s Dad.” A Hollywood icon, he has appeared in scores of movies over more than four decades, including romantic comedies, riveting dramas, and everything in between.

Katalin Karikó

Doctor of Science

An intrepid biochemist fascinated by the therapeutic potential of messenger RNA, Katalin Karikó is a professor at the University of Szeged and adjunct professor of neurosurgery at the University of Pennsylvania’s Perelman School of Medicine. A native of Hungary, she received her bachelor’s degree and Ph.D. from the University of Szeged. She worked at the Hungarian Academy of Sciences before immigrating to the U.S., where in time she joined the Perelman School of Medicine to investigate how RNA could activate the immune system. With Drew Weissman, she discovered how to engineer mRNA so that it can be used to produce desired proteins after being introduced into mammalian cells. This innovation propelled the COVID-19 vaccines developed by Pfizer-BioNTech and Moderna and holds promise for treatment of many other diseases. One of Time’s 2021 “Heroes of the Year” and Carnegie Corporation of New York’s 2021 “Great Immigrants,” she has received the Japan Prize, the Canada Gairdner International Award, the Breakthrough Prize in Life Sciences, the Lasker-DeBakey Clinical Medical Research Award, and the National Academy of Sciences’ Kovalenko Medal. She served as senior vice president of BioNTech from 2013 to 2022.
