Overview

My research uses a bedside-to-bench-to-bedside approach to translate novel immunotherapies for high risk leukemias and to understand and influence complications of hematopoietic cell transplantation (HCT), such as graft versus host disease and graft failure. I recently received R01 funding to use blood and imaging biomarkers to identify graft failure after transplantation. The imaging modality is an investigational nuclear medicine modality, F18-labeled thymidine, which we previously showed identified subclinical engraftment early after HCT. 

I have two projects in the space of immunotherapy: a genetically modified T cell platform and one that relies on expanded T cells specific for tumor antigens.  We are initiating a novel chimeric antigen receptor T cell therapy within Children's Healthcare of Atlanta (using the Prodigy) with plans to study this novel therapy (thanks to the Peach Bowl LegACy fund).  In addition, thanks to Leukemia Lymphoma Society funding, we are expanding T cells to multiple tumor antigens, enhancing their activity through a novel cytokine release system, to treat relapsed refractory acute myeloid leukemia and myelodysplastic syndrome. These studies will utilize novel biomarkers of disease burden and immune response. Finally, I have conducted biomarker and treatment studies to treat a rare but deadly complication of HCT, lung graft versus host disease, and am fortunate to continue this work with national collaborators.
