I am passionate about discovering the mechanisms that govern protective T cell responses. My approach is to compose comprehensive human T cell profiles: functional capacity -- first and foremost -- phenotype, activation status, differentiation state, and transcription factor expression levels. Of a post-modern philosophy, I embrace the complexity of the T cell; I strive to understand how all its components function to form a coordinated response. Comparative analyses of profiles between human subjects who are sick vs. healthy, treated vs. untreated, vaccinated vs. placebo/unvaccinated, amidst acute vs. chronic infection, etc… identify the salient immune factors for disease pathogenesis and/or host protection. The fruit of these analyses is vital for innovation in patient immune surveillance, therapeutic strategy, and vaccine design and evaluation.
