Cell Growth Signalling in Space
I study how individual cells sense and respond to environmental changes. My particular focus is the Target of Rapamycin (TOR, or mTOR) kinase, which adjusts cell growth in response to diverse external stimuli such as nutrients, hormones and stresses.
TOR regulates a wide range of cellular processes operating at diverse subcellular locations ("organelles"). I want to understand how TOR receives signals from, and sends signals to, different locations. By combining various techniques of genetics, biochemistry, cell biology and bioinformatics in yeast and mammalian cell models, our lab tries to fill the existing gap between the signalling and the organelle research fields.
