Silvia studies how plants are affected by climate change and how this in turn impacts the world's carbon cycle and feeds back to the climate. She uses land surface models to understand current plant and ecosystem observations and make predictions about the future. Silvia completed her PhD at the University of Edinburgh in 2013, where she built a global model of leaf phenology. After that, she spent 2 years at Microsoft Research Cambridge in the Computational Ecology lab, looking at general models of crop growth. From 2015 to 2022 she was a researcher at the Max Planck Institute for Biogeochemistry, where she contributed to the QUINCY model and started looking at ecosystem nutrient limitation and effects of elevated CO2 on plant physiology. She joined the college in summer 2022.

My research focuses on process based mathematical models of terrestrial ecosystems, which are a component of the Earth System Models used to create future climate predictions. My specific interest is in including more ecological and physiological realism in such models, while still keeping the implementation simple enough that it is computationally tractable at global scales and usable in a world of limited data. Such ecologically realistic models reduce the uncertainty in the future carbon cycle and potentially allows us to predict linkages between ecosystem carbon storage and terrestrial biodiversity. I am one of the main developers of the QUINCY model which was built with the specific aim to allow such new, more realistic process representation to be easily built and tested. QUINCY is now used successfully across research teams in four countries, with various scientific focuses ranging from Arctic ecosystems to impacts of extreme events. QUINCY is incorporated into the ICON Earth System Model and will produce simulations for the next IPCC report.
