Autophagy is an intracellular recycling process that promotes stress adaptation and cell survival. Our research program explores the contributions of autophagy to proteostasis, normal development, and cancer progression with a focus on breast and pancreatic cancers. We are also investigating the therapeutic potential of autophagy modulation in these cancers.
