Meet Dr. Len Zon ’79

Zon, who was elected to the National Academy of Sciences in 2022, uses zebrafish to study human blood diseases and melanoma.

Dr. Len Zon ’79, the director of the stem cell program at Boston Children’s Hospital and the Grousbeck Professor of Pediatric Medicine at Harvard Medical School, first developed a taste for research as a chemistry major at Muhlenberg.

“It’s very important to be exposed to the process of research and to have goals,” says Zon, who was among the earliest adopters of the zebrafish model to study human disease. “The faculty at Muhlenberg were so fantastic, working directly with me and fostering my excitement, my enthusiasm, my intuition, and it really helped me form as a scientist.”

Zon is well known for his groundbreaking work with zebrafish: His peers elected him to the prestigious National Academy of Sciences in 2022 and, since 1993, he’s been a Howard Hughes Medical Investigator, an honor reserved for the top 300 scientists in the country.
