Dr Imma Oliveras

Departmental Research Lecturer in Ecosystems Science and Deputy Programme Leader on Ecosystems


Imma’s research interests are to decipher how and why tropical vegetation structure and dynamics changes across abiotic gradients and what are the consequences of these changes at the community and at the ecosystem scale. As such, her work focuses on exploring how changes in the abiotic conditions driven by global change – and particularly increases in extreme drought events and modified fire regimes – affect plant functional traits and how this aggregates to ecosystem functioning.

She did her PhD on Environmental Sciences in the Autonomous University of Barcelona, with a thesis focuses on fire ecology of Mediterranean ecosystems. She worked at the University of São Paulo (Brazil) as a Beatriu de Pinós Research Fellow (2007-2009), at the Ecosystems Lab as a postdoctoral researcher (2009-2013) and at Wageningen University (Netherlands) as a Marie Curie Research Fellow (2013-2015). During this time she performed research in Brazil, Peru and Ghana related to fire effects on tropical ecosystem dynamics using a of methodologies from field observations, experimental manipulations to remote sensing.
