Welcome to the

& Metabolism
Research Team

Light sensing, absorption, and derived metabolism
in photosynthetic organisms

The Light, Photosynthesis & Metabolism (LP&M) team aims to advance understanding of the biological processes that photosynthetic organisms use to manage their energy resources. We explore the dynamics of these processes from the molecular level to the cellular level following a multidisciplinary approach.


About us

The Light, Photosynthesis & Metabolism (LP&M) team belongs to the Cell & Plant Physiology Laboratory within the Biosciences and Biotechnology Institute of Grenoble. The Cell & Plant Physiology Laboratory is a mixed research unit bringing together scientists working for CNRS (French National Centre for Scientific Research), CEA (French Alternative Energies and Atomic Energy Commission), INRA (French National Institute for Agricultural Research) and the University of Grenoble Alpes.

The three main research axes of LP&M are:

  • Light signaling, utilization and dissipation (i.e. light function as a signal, an energy source and a dangerous substrate)
  • Redox regulation of electron flow-Ions in photosynthesis
  • The role of organelle interaction (mitochondria <-> chloroplast) in optimizing carbon assimilation and downstream metabolism.

We are generating knowledge which, in particular in the case of unicellular microalgae, can also be exploited for domestication (growth in photobioreactor, production of metabolites of economic interest). (See industrial partnerships)

The LP&M team gathers scientists from different countries (France, Greece, Italy) complementary skills (molecular biology, cell biology, biochemistry, biophysics) and research backgrounds to study fundamental biological questions with a truly multidisciplinary approach.

The LP&M team collaborates with many teams in France and abroad.
