My research focuses on several topical themes in fundamental and applied ecology, including the determinants of biodiversity structure and function from genes to ecosystems, the combined influence of multiple anthropogenic stressors on communities and ecosystems, and the management and conservation of biodiversity and ecosystem services in the face of global change. I perform my research predominantly in streams and rivers, combining `natural" field experiments with manipulative experiments at a range of scales, from whole streams to mesocosms. By advancing knowledge and connecting science to policy, my research seeks to improve the management, conservation and restoration of aquatic ecosystems in the face of global change. Dr Piggott was named the 2019 Irish Research Council Early Career Researcher of the Year and is a recipient of the inaugural Irish Research Council Laureate Award (see https://www.tcd.ie/news_events/articles/pioneering-trinity-ecologist-wins-irc-early-career-researcher-of-the-year/). He has authored >40 publications (2088 citations, h-index 21, i10-index 23) and independently obtained >€2m in research grants (>€15m in collaborative funding). He currently supervises five PhD students, four Post Docs and a Research Assistant working across 13 collaborative projects funded by: H2020, Belmont Forum/BiodivERsA, Water JPI, Irish Research Council, German Research Council, NERC UK, EPA Ireland, Marine Institute Ireland and Enterprise Ireland. The latter includes being the sole Irish funded PI on AQUACOSM+, a €10m H2020 INFRAIA project for the Network of Leading Ecosystem Scale Experimental AQUAtic MesoCOSM Facilities Connecting Rivers, Lakes, Estuaries and Oceans in Europe and beyond.
