Description of Research Expertise

Our lab investigates two lines of research. The first involves investigating the mechanisms of tumor immune surveillance and ways to harness the activity of innate lymphocytes for cellular cancer immunotherapy. There are currently 3 ongoing projects relevant to this line of investigation: 1) Investigating how to trigger endogenous natural killer T and natural killer cell anti-tumor responses for cellular immunotherapy; 2) Delineating the immunometabolic features of Natural killer T cells; 3) Delineating the neuroblastoma immune microenvironment and how to modulate this for therapeutic purposes. The second line of research involves increasing our understanding of the immune pathogenesis of pediatric hyper-inflammatory syndromes, including those resulting from genetic lesions, as well as those induced by infections (e.g. COVID-19) or cancer immunotherapy (e.g. CAR-T cell therapy).
