Nicolas Cassar's research focuses on environmental biogeochemistry and physiology, with the objective of constraining the mechanisms governing carbon cycling and climate. Current research interests include ocean carbon cycles and productivity; carbon acquisition mechanisms in marine phytoplankton and implications for climate change and paleo-CO2 reconstruction; and global carbon cycle and ocean-atmosphere fluxes. His scientific approach is interdisciplinary, integrating field observations, laboratory experiments, modeling and theory.
