OUR RESEARCH
We are interested in identifying novel pathways that enable cellular and organismal adaptation to metabolic stress and changes in environmental conditions. We also study how these pathways go awry in human diseases such as cancer, neurodegeneration and metabolic syndrome, in order to engineer new therapeutic modalities.
To address these questions, our lab uses a multidisciplinary approach to study the biochemical functions of the lysosome in vitro and in vivo. Lysosomes are membrane-bound compartments that degrade macromolecules and clear damaged organelles to enable cellular adaptation to various metabolic states. Lysosomal function is critical for organismal homeostasis—mutations in genes encoding lysosomal proteins cause severe human disorders known as lysosomal storage diseases, and lysosome dysfunction is implicated in age-associated diseases including cancer, neurodegeneration and metabolic syndrome.
By developing novel tools and harnessing the power of metabolomics, proteomics and functional genomics, our lab will define 1) how the lysosome communicates with other cellular compartments to fulfill the metabolic demands of the cell under various metabolic states, 2) and how its dysfunction leads to rare and common human diseases. Using insights from our research, we will engineer novel therapies to modulate the pathways that govern human disease.
Functional characterization of the lysosomal molecular content
Our previous work has revealed surprising dynamics in lysosomal content (proteome and metabolome) as part of the response to changes in environmental conditions. These molecular events are necessary for the cellular adaptation to changes in nutrient availability and metabolic state, which is consistent with the role of the lysosomes in these processes. Our lab will further dissect the physiological roles of the lysosome by mapping and
functionally characterizing its molecular components under various metabolic states in tissue culture cells and in animal models. Using genetic and molecular tools we will then perform followup studies to establish the role of the lysosome in tissue homeostasis.
