How much can we trust the Living Planet Index?
The Living Planet Index is the headline number for the state of the world's vertebrates, but it's built from patchy data. Explore how we tested its reliability, and which trends need more data.
Postdoctoral researcher at Justus Liebig University Giessen & Ph.D. from University College London (CBER / ZSL / RSPB). Creator of the b3gbi R package for GBIF biodiversity data cubes.
Fiction and essays that engage both the intellect and the heart. Explore the suspense thriller Entering Darkness, short stories, and thought-provoking articles on science, faith, and human empathy.
Developing robust quantitative indicators and open-source software tools to track global biodiversity change—from deep-sea mesopelagic fish communities to continental occurrence data cubes and the Living Planet Index.
Notice how the three silhouettes in the landing page artwork reflect the three scales of my scientific research.
Transforming raw citizen-science and museum occurrence records from GBIF into standardized gridded data cubes to measure species richness, taxonomic distinctness, rarity, and Hill diversity across space and time.
Investigating how data deficiency, patchy geographic sampling, and taxonomic bias affect headline policy metrics like the Living Planet Index (LPI), and designing sampled & diversity-weighted approaches.
Studying latitudinal transitions, spatial distribution, and larval fish assemblages of mesopelagic fishes across the eastern central Atlantic, linking oceanographic drivers to marine community structure.
