Dr Natalie Oram

Natalie is a research scientist funded via a Research Leaders 2025 (Marie Skłodowska-Curie grant agreement No 754380) fellowship. She is working in collaboration with Dr. Fiona Brennan, Teagasc, Ireland, Prof. Richard Bardgett, University of Manchester, UK, and Prof. Michael Bahn, University of Innsbruck, Austria on a project entitled ' Remembering the drought: how soil memories affect grassland resilience' which focused on the impact of drought on grassland systems. The frequency and severity of droughts is increasing in our changing climate. Drought can have a lasting effect, by disrupting the interactions between plants and the soil microbial community. In this project she aims to determine how pervasive these disruptions are: how a drought legacy alters the soil microbial community’s structure and function, plant-microbe interactions, and plant resilience to a subsequent drought. Prior to her current fellowship, Natalie completed a BSc. in Agriculture Science (University of Guelph, Canada), a MSc. in Agroecology and a PhD. in Plant Ecology (Wageningen University, the Netherlands)
