Cordelia Roberts

Cordelia Roberts is a Research Associate in the Department of Life Sciences at Imperial College London's Silwood Park campus, part of the Faculty of Natural Sciences. Her work focuses on microbial interactions with marine particles and their role in carbon cycling. She leads projects like the NERC-funded 'PARTITRICS' and EU-funded 'SEA-QUESTER', exploring particle-type impacts on carbon storage in the North Atlantic and Arctic regions.

Dr. Roberts holds a PhD from the University of Plymouth. Her research combines fieldwork, experiments, biogeochemical analysis, and molecular biology to study bacteria, archaea, and microbial eukaryotes. Key interests include particle heterogeneity, microbial diversity on particles, and effects of microplastics on ocean carbon dynamics.

Her recent work emphasizes the 'particlescape' concept, mapping microbial community diversity across marine particles. Projects investigate how particle fragmentation and microplastics alter organic matter respiration, with implications for climate models. She collaborates across disciplines to address critical oceanography questions through innovative experimental frameworks.
