Bruno Cremella’s main research subjects include ecophysiology of algae and cyanobacteria, biogeography and niche structuring forces of phytoplankton communities, in situ and laboratory pigment measurement techniques, photosynthetic ecology, and structural drivers of carotenoid functional diversity and evolution. Systems he has studied in the past include algal cultures, lake and reservoir water columns, and polar cyanobacterial mats. He is currently working on solar-induced fluorescence profiles based on autonomous floats as a refinement tool for global ocean photosynthesis modelling. His main interests are the links between global photosynthetic phenology and the diversification of plankton ecophysiology.
