Research Interests
Understanding how extracellular cues are linked to gene expression is a fundamental challenge in biology, and more specifically, innate immune signal integration is central to understanding healthy versus aberrant regulation of inflammation. My laboratory uses quantitative approaches to address these problems, with major projects including (1) computational modeling of signaling-to-transcription in macrophages, (2) interrogating tissue-specific macrophage signaling, and (3) dissecting molecular determinants of monocyte and macrophage inflammatory function. We use experimental approaches, together with both data-driven and mechanistic modeling to integrate transcription factor activity, phosphorylation, and transcriptomic data to explore signaling mechanisms that shape stimulus-specific macrophage function. These efforts will yield insights into dysregulation of signaling and inflammation, while informing therapeutic strategies.
