Research Interests
Macrophages are fascinating cells that control diverse biological and physiological processes. Our research focuses on how cellular metabolism regulates macrophage functions, including the interplay between metabolic processes and the signal transduction pathways that regulate macrophage activation, and mitochondrial metabolism and its influence on chromatin. We aim to elucidate the mechanisms by which cellular metabolism regulates macrophage functions in diverse contexts, of relevance to the many physiological and pathophysiological contexts in which macrophages play a role.
