I am a plant geneticist and biologist, I have always been interested in how plants adapt to environmental changes and how plant hormones mediate this adaptation. I am currently investigating how information on the energy state of plants is transferred to growth pathways through DELLA proteins. In particular, we will test whether these proteins are stabilized and destabilized by the signaling module SnRK1-TOR, key to interpreting the energy state of the plant.
