Our team seeks to determine the adaptation strategies of cells to nutritional stresses, such as nutrient deficiencies or inhibition of metabolism. Our work is at the intersection of cell biology, cell signaling and metabolism, using the yeast Saccharomyces cerevisiae as a model.
We have many tools and expertise to perform experiments in the field of protein localization, post-translational modifications, interactions, proteomics, genetic screens (including a RoToR Robot by Singer and several genome-wide collections) etc.
