Kieran is an environmental scientist with a particular interest in freshwater systems. His research is split into two key areas:

  1. assessing the impacts of environmental change (i.e. glacier retreat and droughts) on the structure and function of aquatic ecosystems, and;
  2. unravelling dissolved organic matter and nutrient dynamics in anthropogenically modified river systems (i.e. urban and agricultural).

His research is largely empirically based and involves the use of in-situ monitoring across environmental gradients in real ecosystems, alongside mesocosm scale experimentation. He has also developed new techniques for high-frequency monitoring of organic pollution using fluorescence based, in-situ sensors.
