Objective:

The objectives of this research project are to: (1) determine whether the effects of simultaneous multiple perturbations are predictable, given the knowledge of the effects of individual perturbations; and to(2) determine whether there are interactions among perturbations.

Approach:

I am using a combination of experimental and modelling approaches to investigate the combined effects of increased nutrients and dissolved humic organic matter on phytoplankton communities.
