Research Interest 

I am interested in understanding the mechanisms and cell types that control immune activation and harnessing the immune system to combat human disease. My research focuses on the T regulatory type 1 T cells. This subtype of T cells is generated in the periphery and produces high amounts of IL-10, leading to immune regulation. We are interested in better understanding the ability of Tr1 cells to kill myeloid cells, in particular Acute Myeloid Leukemia (AML) cells. I have generated Tr1 cell lines using lentiviral transduction of IL-10 and am in the process of using these cell lines to determine which primary pediatric patient AML subtypes are killed by Tr1s. By characterizing the surface marker expression of sensitive AML subtypes, I can identify candidate molecules that contribute to Tr1 mediated killing. I am also researching the molecular identity of Tr1 cells. In my free time, I enjoy being outdoors, running, brewing beer, and playing board games.
