Uppsala University

Sweden, Partner

Uppsala University is a broad research university with a strong international position, with around 7,600 employees and 53,000 students.

The Department of Organismal Biology teaches and studies evolution, development, and function in whole organisms. The Physiology and Environmental Toxicology programme is a growing, vibrant research environment where experimental models and molecular tools are used to study and understand cellular and molecular mechanisms in animals and plants that underlie whole organisms’ physiology, development, and responses to the environment.

In ExpoSignalz, Uppsala is involved in screening chemicals for neurotoxic effects and their ability to cross the blood-brain barrier, using a combination of in vitro models and conducting a literature review. The team are also studying relevant molecular pathways and epigenetic effects to increase our mechanistic understanding of how chemicals are involved in neurodegeneration.

Joëlle Rüegg is Professor of Environmental Toxicology at Uppsala University, Sweden. After her Master’s in Neuroscience and a PhD in Biochemistry, she moved her research focus to epigenetic effects of endocrine-disrupting chemicals in the context of brain development. She has been working in this field for 20 years, and has been leading large EU-funded research projects contributing to improving hazard and risk assessment of endocrine-disrupting chemicals and their mixtures.

Andrea is a researcher in Environmental Toxicology at Uppsala University, with a focus on how environmental pollutants affect brain health. She holds a PhD in Environmental Toxicology, and her research centres on developing non-animal testing methods and improving chemical risk assessment. By using in vitro test systems, she aims to generate data that supports safer chemical use and more protective regulations.

In addition to her research, she teaches and supervises students at both undergraduate and graduate levels. Andrea is particularly interested in how science can inform policy and in finding practical ways for research to contribute to public and environmental health.
