Personal profile

Research interests

I am interested in understanding the interplay between the resource use of individual organisms and the dynamics of their populations and communities. Organisms display substantial flexibility in their rates of energy intake and expenditure - how is this plasticity mediated by the biotic and abiotic environment and how does it affect community function? 

I approach these questions by interfacing physiology and ecology. Specifically, I combine physiological measurements of energy flux with experimental manipulations of populations and communities, using marine invertebrates and algae as model systems, to investigate the interactions between the size of organisms, their densities and energy use.
