Research Interests:
The Langdon Laboratory’s mission is to elucidate the intricacies and mechanisms underlying how different oncogenic events shape cancer cell fate decisions in pediatric sarcomas with the goal to better tailor pharmacological interventions for these devastating tumors. We are initially focused on Ewing sarcoma. Ewing sarcoma is a devastating pediatric bone cancer with no new advancements in therapeutic options for these patients in decades. The Laboratory uses a combination of molecular biology techniques and pharmacological intervention strategies to assess different cooperating drivers that facilitate sarcomagenesis. The overarching goal of the Laboratory is two-fold: to perform high impact basic science to investigate the mechanistic determinants of Ewing sarcoma development and to translate that work into transformative care for these patients.
