Research
People in my lab are interested in the ecology and evolution of populations and communities. Our premise is that evolutionary change may be rapid and that the distinction between ecological and evolutionary time scales is often arbitrary.

To study eco-evolutionary dynamics we use aquatic model organisms and conduct controlled experiments in the laboratory and in the field. We believe that this approach, combined with mathematical modelling, will contribute to a better understanding of the dynamics of real ecosystems such as lakes and streams. It is unlikely that ecologists will ever be able to make predictions of the dynamics of field systems, if they fail to predict the behaviour of a simplified laboratory system.

  • Eco-evolutionary dynamics in chemostats
  • Ecology and evolution of parasite-host relationships in streams in Trinidad
  • Ecological and evolutionary consequences of elevated CO2
  • The paradox of the plankton - competitive coexistence under equalizing and stabilizing mechanisms
  • Aquaculture, mussels and nutrients (AquaMaN)
  • Rotifers as model organisms and as study objects in their own right
