Current Research

Elevated nutrient concentration in freshwater systems is a global problem that impacts water quality and the ecology of our rivers and streams. To date, most research on the effects of nutrient pollution on aquatic insects has been on the larval life-stage. Freshwater pollution and in particular, fine sediment and phosphates may have a far greater effect on the egg stage of development due to the immotile state increasing vulnerability.

My PhD research aims to investigate the effects of chronic and pulse nutrient and sediment pollution on the embryonic development of mayfly eggs and investigate if these effects are contributing to the decline of these keystone species from England's chalk river systems.
