Dr Dall'Olmo is interested in improving our understanding of ocean biology and biogeochemistry by exploiting optical measurements in-situ and from space. His research spans from devising and improving optical proxies of biogeochemical variables (e.g., particulate organic carbon) to investigating ecological and biogeochemical processes using optics (e.g. the biological carbon pump). Dr Dall'Olmo leads the UK Bio-Argo programme in collaboration with the UK Met Office, the British Oceanographic Data Centre (BODC) and the National Oceanography Centre (NOC).
