Principal Investigator and Senior Research Associate
I have moved to Biological Sciences at the University of Southampton.
My Southampton webpage is here and my new email address is r.j.morris(at)soton.ac.uk
I am now a Senior Research Associate in the Zoology Department at Oxford University, and will continue to be an active PI and DPhil supervisor in CERO, whilst I have current grants and research group members based in Oxford. New students and researchers will be recruited via the University of Southampton.
I lead a research group quantifying the structure, dynamics and functioning of ecological communities, and investigating how they respond to environmental change. I have a long-standing interest in transferring ecological theory into the field to test predictions about how ecological mechanisms, including density- and trait-mediated indirect interactions, structure networks. I use a range of empirical and quantitative approaches, particularly rigorous, large-scale manipulative experiments. Much of my work involves insects, primarily herbivorous insects and their parasitoids and host plants, and takes place in natural and human-modified tropical rainforests.
I am leading a socio-ecological collaboration promoting the resilience of subsistence farming to El Niño events in Papua New Guinea. I am also a principal investigator in the LOMBOK consortium, working at the Stability of Altered Forest Ecosystems (SAFE) Project Site in Borneo. We are combining surveys of biodiversity and biogeochemistry along a gradient of forest modification with in situ manipulative experiments, to gain a mechanistic understanding links between biodiversity and ecosystem functioning.
