Welcome to the Light, Photosynthesis and Metabolism team!
The Light, Photosynthesis & Metabolism (LPM) team (founded in 2015) belongs to the Cell & Plant Physiology Laboratory within the Interdisciplinary Research Institute of Grenoble.
OUR MAIN RESEARCH FOCUS is to understand the adaptive responses of phototrophs to different trophic lifestyles (phototrophy, mixotrophy, symbiosis) and environmental constraints. Our main models are the microalgae Phaeodactylum (diatom), Galdieria (rhodophyte), Phaeocystis (Haptophyte), Chlamydomonas (Chlorophyte), and the plant Arabidopsis.
OUR MAIN APPROACH is the ‘next-generation physiology’ that combines photophysiology with integrative metabolism at different scales, from the cell to the protein level.
We are a multidisciplinary team with complementary skills (molecular biology, imaging, biochemistry, modeling) and different backgrounds (eco-physiology, cell biology, biophysics, mathematics).
Our Laboratory belongs to CNRS (French National Centre for Scientific Research), CEA (French Alternative Energies and Atomic Energy Commission), INRAe (French National Institute for Agricultural Research) and the University of Grenoble Alpes. The LPM team collaborates with many teams in France and abroad.
