Jennifer Amengual, MD is an Associate Professor of Medicine at Columbia University in the Division of Hematology and Oncology. As a physician-scientist, her research goals are to directly translate observations and concepts developed in the laboratory to rational targeted therapies for patients with lymphoma. Dr. Amengual has led many investigator-initiated trials based on data generated in her laboratory through the NCI Cooperative Group Networks, SWOG and ETCTN. Columbia University is a tertiary care center that performs a high number of organ transplants and has an enrichment of PTLD patients. This has generated great interest in how to improve screening and treatment for these patients. Dr. Amengual has spearheaded a PTLD working group that encompasses transplant, infectious disease, lymphoma and cellular therapy specialists from both the adult and pediatric groups. This has led to the development of several studies providing the foundation for the proposed clinical trial.
