Description of Research Expertise:
My laboratory incorporates both basic science research and clinical investigation to examine the role of innate immunity, in particular monocytes/macrophages, in regulating tumor biology in pancreas cancer as well as other upper gastrointestinal malignancies. Our central hypothesis is that macrophages are key regulators of tumor biology.
Clinical research in the laboratory uses patient-derived samples to understand the role of macrophage biology in metastatic disease and therapeutic efficacy.
Preclinical research in the laboratory uses a genetically engineered mouse model of pancreas cancer in combination with advanced imaging strategies to study macrophage biology within the tumor microenvironment. This preclinical research platform allows for the study of basic immune biology within the tumor microenvironment as well as the rapid screening of novel immunotherapeutic strategies, including cell and gene therapies, for the treatment of cancer.
Studies in the laboratory focus on understanding 1) the signaling pathways that regulate cross-talk between macrophages and tumor cells in vivo, 2) the role of hematopoietic and non-hematopoietic cells in regulating macrophage biology within tumors, 3) the cellular trafficking of macrophages to primary and metastatic lesions, 4) strategies to harness macrophages for anti-tumor therapy, and 5) the impact of chemotherapy/radiation therapy on macrophage biology within tumors.
