A. Thomas Look

A. Thomas Look is Professor of Pediatrics at Harvard Medical School and Vice-Chair for Research, Pediatric Oncology, Dana–Farber Cancer Institute. He is a pioneer in the use of zebrafish in cancer research and made major contributions to the understanding of leukemia and neuroblastoma biology and pathogenesis.

Education
Look received a BSE in Chemical Engineering from University of Michigan, Ann Arbor, in 1971, followed by a degree in medicine (MD) from the same university in 1975. He undertook most of his training in pediatric oncology at St. Jude Children's Research Hospital, Memphis, before becoming Professor of Pediatrics at University of Tennessee, College of Medicine in 1987. In 1999 he moved to Dana–Farber Cancer Institute to become Vice Chair for Research in Pediatric Oncology and Professor of Pediatric Oncology at Harvard Medical School.
