Research Summary

Dr. Ladle is a practicing pediatric oncologist and translational immunology researcher who has the goal of developing novel immunotherapies for the treatment of pediatric malignancies. His research seeks to understand mechanisms of immune tolerance in pediatric sarcomas and developing successful combination immunotherapies that will successfully treat sarcoma patients. He is working on translational projects combining immunotherapy with chemotherapy, epigenetic modifying agents and innate immune system adjuvants. Dr. Ladle has extensive expertise in immunology techniques – including both mouse and in vitro cell culture, multi-color flow cytometry and molecular techniques.
