Cancer Research Interest

• Research Interest Statement: I am interested in exploring the molecular mechanisms T cells utilize to sense and adapt to environmental stress, focusing on the immune control of cancer. My work utilizes specialized proteomic approaches to established immune monitoring strategies and to inform the development of cellular therapies.
