Dr Katie Reilly is an environmental scientist with a focus on ecotoxicology and anthropogenic stressors in aquatic environments. Katie also has a keen interest in science communication and public engagement centered in environmental issues, often with a focus on microplastic pollution effects, and has experience working with a range of audiences.


BSc (Hons) Environmental Science

MSc Applied Marine Science

PhD Environmental Science


Dr Katie Reilly is a post-doctoral researcher exploring how particle-based pollutants, such as microplastics and nanomaterials, can change in the environment and the effects that this can have on the ecosystem. Katie undertook her PhD at the University of Birmingham on how increasing the environmental realism of microplastic studies changes their potential toxicity to Daphnia, and how combined environmental pollution (such as exposure to mixtures of chemicals and plastics) can lead to variable toxicity - highlighting the complexity of this issue.  Katie is currently working on the EU-Funded RiskGONE project developing new methods to assess the environmental risks from nanoscale materials, and is involved in a NERC discipline hopping project on the differences in the epigenetic changes in Daphnia exposed to ‘traditional’ plastics compared to newer bioplastics.
