Biography

Dr. Endicott completed his B.A. in Molecular Biology and Chemistry in 2011. He earned his Ph.D. in Genetics from Yale University in 2016. Following the completion of his Ph.D., Dr. Endicott completed a postdoctoral fellowship at the University of Michigan in 2021. Dr. Endicott worked as a Research Investigator at the University of Michigan until 2024, when he joined UNM as an Assistant Professor.

Personal Statement

My multi-disciplinary research uses a combination of quantitative proteomics, biochemistry, microscopy, cell biology, and mouse studies to address questions pertaining to chaperone-mediated autophagy (CMA). CMA is a selective form of lysosomal proteolysis, which targets individual proteins for lysosomal degradation, independent of vesicle fusion. Through selective proteolysis of rate-limiting enzymes, CMA regulates essential metabolic processes, such as glycolysis, cytoplasmic acetyl-coA production, fatty acid synthesis, and translation at the cytoplasmic ribosome.

My research program addresses two broad questions:
1. How is CMA regulated at the endocrine, cellular, and sub-cellular levels?
2. What are the targets of CMA, and how does their degradation affect metabolism, health, and longevity?
