Biography

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.

Description Of Research Interests

QUINCY (Quantifying the effects of interacting nutrient cycles on terrestrial biosphere dynamics and their climate feedbacks) is a newly developed land surface model with fully coupled carbon, nitrogen, phosphorus and water cycles. QUINCYis built in a modular fashion, and is the ideal tool to test out new hypotheses and model processes. We of course have some new scientific features as well, such as the ability to track carbon and nitrogen isotopes, a short and long-term plant storage pool and decoupling photosynthesis from growth.
