Research Summary

My research program has focused on translating genomic and biochemical discoveries in juvenile myelomonocytic (JMML) and acute lymphoblastic leukemia (ALL) into assays and therapies that can be incorporated into clinical trials. My work in JMML has largely focused on dissecting the genomic landscape of JMML, including descriptions of PTPN11 and CBL mutations and the discovery of CBL as a new familial tumor suppressor gene. From these discoveries, I established molecular diagnostic testing for JMML in the CLIA setting at UCSF, which is now utilized in a clinical trial (#ASCT1221). Within the Children’s Oncology Group (COG), I am currently Chair of the COG ALL committee starting in April 2015 and am responsible for supervising and implementing the next generation of national ALL trials for children, adolescents, and young adults. This appointment in part stemmed from my role as a Study Co-Chair of AALL03B1, the Classification of Acute Lymphoblastic Leukemia, which over enrolled 11,200 children, and my role as Vice-Chair of Biology (2008-2015). My unique expertise is being able to straddle the physician-scientist landscape and collaborate with numerous outstanding clinicians and scientists in order to facilitate cutting edge discoveries into patient care. I am a generous collaborator and deeply believe in the concept of team science. I also have experience in developing and running early phase clinical trials for children with cancer.
