Background

Hannah joined the School of Life Sciences in July 2021. She is a macroecologist with broad research interests covering the spatial and temporal patterns of biodiversity, ecosystem stability and the mechanisms underlying these. Her research has spanned a wide range of taxa from birds to plants to soil micro-organisms.  

After developing an interest in the importance of ecological traits during her MSc at Imperial College London, Hannah completed her PhD at Queen’s University Belfast studying spatial and temporal patterns of functional diversity in UK birds and Scottish plants. Her research positions at University College Dublin and Trinity College Dublin have covered topics including ecosystem stability using remotely sensed data and the contribution of common and rare species to functional diversity, respectively. Her research has been awarded the Elton Prize from the British Ecological Society and the Excellence in Ecology Early Career Researcher from the Irish Ecological Association.
