I am an aquatic ecologist based at Queen’s University, Belfast. My background is in marine environmental monitoring of benthic infauna and phytoplankton assemblages as part of various legislative commitments in the UK. My current research focusses on resolving consumer-resource interactions in aquatic systems using a combination of simulation modelling, laboratory manipulations and field-based methods. I am particularly interested in how biotic and environmental factors modulate interactions to alter the outcomes of predator-prey population dynamics.
