  • Research

    Aging is a combined consequence of increased cellular stress and decreased homeostasis. Our research focuses on basic molecular mechanisms underlying cell homeostasis and stress response. Currently, we are aiming at discovering the molecular mechanisms underlying the sensing, repairing, and clearance of damaged organelles in mammalian cells. We believe there is a unifying principle behind these complex stress response processes and that spatiotemporal lipid signaling is one such general principle. Our long- term goal is to identify the molecular basis of aging with a focus on lipid signaling and to develop pharmacological strategies to fight aging and age-related diseases.
