After receiving a M.S. in Environmental Sciences from the University of Pisa in 2003, Trivellone received her Ph.D. in biology from the University of Neuchâtel in 2016. She worked as a research assistant at the Federal Institute for Forest Snow and Landscape Research (WSL) and Agroscope in Switzerland. In 2018, she worked at the Illinois Natural History Survey, University of Illinois (US) as a postdoctoral fellow for 5 years. Since 2023, she has been working at the Illinois Natural History Survey (University of Illinois at Urbana-Champaign) as an assistant research scientist in Vector Ecology.

Academic Interests

Valeria Trivellone is an ecologist and evolutionary biologist and her work ranges from field studies of the evolution of host-pathogen systems in natural and agricultural habitats to foundational studies of the ecological theory of community assembly and coexistence.
Her current focus is integrating evolutionary principles with ecological theories into understanding the relationship between global changes (e.g. land use) and emerging disease using the Stockholm Paradigm. From such insights stems a proactive policy proposal (DAMA protocol) to anticipate pathogen outbreaks to reduce the disease costs of food production.
