Plant Resilience Under Climate Threats

During the 21st century Climate change and Food sustainability will reach the point of maximum danger. The Challenges represented by the impact of climate change on the terrestrial biosphere and its repercussions for supplying food to the projected 9-10 billions people worldwide by 2050 will be unprecedented. On the one hand, food yields should continue increasing to keep with population growth. On the other hand, plant species will have to adapt to the fast changes in climate and increase their resilience to pest, temperature and water limitations. These environmental changes are already threatening crop yield but their long-term impact on ecosystems and food productivity remains unclear. My general interest lies in the biochemical and physiological resilience of plants to these environmental stresses. In particular, I am interested in understanding how kinetics regulation and substrate requirements of key enzymatic processes define plant productivity and control their survival. These key enzymatic processes are essential to accurately predict current and future impact of climate change on ecosystem productivity and biogeochemical as well as defining new target for crop improvements in their future resilience to Climate variabilities.

My research combines theoretical and empirical approaches to disentangle the complexity of plant metabolic pathway. The empirical approach includes field measurements in temperate and sub-arctic deciduous ecosystems as well as greenhouse environmental manipulation. The theoretical approach includes assessment of current Terrestrial ecosystems models' limitations and design and sensitivity-tests of new parameterizations for respiratory COproduction. 

To investigate how to takle the needs of a growing population for healthy and locally grown food, I developped the Princeton Vertical Farming Project. This project aims to present vertical farming as part of the solution and to re-establish the connection between the growing industry of Vertical Farms and Academic Research. We investigate multi-aspect of vertical farms sustainability on the business development side but also engineering, environmental and biological sides.
