Research Interests

  • The primary focus of my research is the investigation of the cellular regulation of T-cell immunity and tolerance, and how membrane-bound costimulatory molecules control T-cell function and immune disease.
  • Membrane-expressed receptors termed costimulatory molecules are essential for T-cell responses and play important roles in the immune system to guard the body against harmful microorganisms. There are a number of costimulatory molecules that control T-cell activity. Understanding how these molecules function is likely key to understanding how immune disease and inflammation are controlled and how immune responses to malignancies and infectious pathogens can be generated.
  • Most effort is being expended to develop and optimize strategies for utilizing highly reactive T lymphocytes for cell-based therapies. Because of the plasticity and potentially unlimited capacity for self-renewal, stem cell-derived T lymphocytes have great potential in the treatment of diseases (e.g., chronic viral infection, cancer, and autoimmune disease). In addition, the function of T lymphocytes is tightly associated with metabolic reprogramming. Combination of development of stem cell-derived T lymphocytes with metabolic reprogramming by unique immune-modulatory targets will contribute important information in the areas of vaccine design, autoimmune therapy, and immune-based anti-cancer strategies.
