Our laboratory aims to study the biochemistry that governs host-microbe interactions. From a systems scale perspective, we focus on studying bacterial pathogenesis, host responses to infection, and the impact of the microbiome on health and disease. At its core, the laboratory applies multiplexing quantitative proteomics to simultaneously track thousands of protein dynamics and associated post-translational modifications in an accurate and high throughput fashion. We then interface microbiology techniques to characterize important factors identified during these interactions. When the opportunity arises, translational studies of therapeutic value are undertaken in tissue culture and murine models. This information is then used to design novel strategies for the treatment of human infectious diseases.
