Dr. Langenau is an Associate Professor at Harvard Medical School and Associate Pathologist at the Massachusetts General Hospital. Dr. Langenau is joint-appointed through the Department of Pathology, the Cancer Center and the Center for Regenerative Medicine at the Massachusetts General Hospital. Dr. Langenau is also a principal faculty member at the Harvard Stem Cell Institute (HSCI) and a member of the Dana-Farber/Harvard Cancer Center. Dr. Langenau runs an active research group that focuses on uncovering mechanisms of progression and relapse in pediatic cancer. He has become a pioneer in using zebrafish to understand human cancer biology. His group has used the zebrafish model to dynamically visualize the hallmarks of cancer in live animals, to develop drug screening approaches to kill relapse-driving tumor propagating cells, and to uncover oncogenic drivers conserved in zebrafish and humans using bioinformatic approaches and cross-species comparisons.
