Research Interests

The study of autophagy (= “self-eating”) has generated tremendous attention due to the recognition that autophagy is involved in multiple developmental processes and various human diseases including cancer. Autophagy is a catabolic cellular process that provides nutrients and energy through lysosomal degradation of cytoplasmic components engulfed in double membrane-bound vesicles known as autophagosomes. Autophagy occurs at basal rates in virtually all eukaryotic cells to fulfill homeostatic functions such as the recycling of long-lived proteins and damaged organelles. Under cellular stress conditions, autophagy is upregulated as an adaptive survival response. Cancer cells may exploit elevated autophagy to survive low nutrient conditions, fuel proliferation, and escape the effects of chemotherapy and radiation treatments. Consequently, autophagy is under investigation as a novel target for anticancer therapy. However, our understanding of the mechanisms by which cells utilize the autophagy pathway to promote both normal development and cancer progression is in its infancy.  To help elucidate these mechanisms, the overall goals of my research program are to identify and characterize regulators of autophagy; investigate the roles of autophagy during normal development; and evaluate the therapeutic potential of autophagy modulation for cancer treatment.

GFP autolysozomes

GFP-LC3 autophagosomes in breast cancer cells.


Current research projects include the following areas of investigation:

  • Autophagy and apoptosis crosstalk in Drosophila and mammalian model systems
  • Autophagy as a therapeutic target in breast cancer
  • Autophagy-related mutations in human cancers
  • Screening for candidate inhibitors of autophagy proteins
