About Me

I am a PhD student at the Marine & Freshwater Research Centre (MFRC), researching the environmental impact of biodegradable and bio-based polymers. My work focuses on understanding how leachates from these materials affect aquatic ecosystems. With a strong passion for ecotoxicology and environmental sustainability, I aim to bridge the gap between biodegradable materials and their real-world ecological consequences.

Background & Education

I earned a First-Class Honours degree in Applied Freshwater and Marine Biology from ATU Galway, where I developed a strong foundation in aquatic ecology and environmental monitoring. My undergraduate research on behavioural changes of hermit crabs when exposed to plastic and bioplastic leachates fuelled my interest in pollution impacts on aquatic systems, leading me to pursue further study in this field.

Research Interests

  • Ecotoxicity of biodegradable and bio-based polymers
  • Leachate chemistry and its effects on aquatic life
  • Sustainable materials and their environmental trade-offs

Current Research

I am currently investigating how bioplastic leachates influence the growth of freshwater algae. By analysing the chemical composition of these leachates and their biological effects, I hope to provide valuable insights into the potential risks associated with biodegradable materials in aquatic environments.

Achievements & Publications

  • ESAI Best Poster Presentation Award, Environ 2025 – Recognised for my research on how exposure to bioplastic leachates impacts growth of freshwater green algae.
