About

I am interested in understanding how genetic and non-genetic factors shape human immune responses to infections and vaccines, with a particular emphasis on how immunity evolves across the lifespan. My research focuses on dissecting host determinants of immune function, developing clinically practical methods to assess immune status, and uncovering the mechanisms driving age-related immune changes—such as the decline in naïve T cell populations and reduced vaccine responsiveness in older adults. By identifying key molecular and cellular pathways underlying these changes, I aim to reveal actionable targets to enhance immune function, particularly in aging populations. Ultimately, my work aspires to inform strategies that strengthen immunity, improve infection control, and optimize vaccine efficacy across both general and older populations.
