Alex Kentsis, MD, PhD, is a pediatric oncologist and cancer biologist who treats children and young adults with leukemias and refractory solid tumors. In particular, he is interested in developing treatments that maximize the success of currently available therapies and devising new therapies that are precise, curative, and safe. His research takes advantage of modern technologies to improve our understanding of the biologic causes of blood and solid tumors. Together with colleagues, he has made discoveries about new therapeutic targets in cancer cells, mechanisms by which cancer cells can evade new treatments, and improved strategies to overcome treatment resistance. This work has been recognized by the Scholar Award from the American Society of Hematology, the Investigator Award from the Damon Runyon Foundation, the Scholar Award from the Rita Allen Foundation, and the Arceci Innovation Award.
