Sandra Bouwhuis is an evolutionary ecologist with a specific interest in the causes and consequences of within-individual change in life-history traits and between-individual variation in life-history strategies. She mostly conducts analyses on long-term individual-based datasets collected in wild animal populations. She has published 47 peer-reviewed papers in high-ranked international journals, including Nature and Science and has an H-index of 23. She has obtained €1.113.590 in grant and prize money. She is a handling editor for Journal of Ornithology, a member of the advisory boards of the German Ornithological Society and SPI Birds, and a member of the British Ecological Society, German Ornithological Society and Society for the Study of Evolution. She served on the editorial board of Journal of Animal Ecology (2017-2019; 52 manuscripts) and as a Council member of the Waterbird Society (2016-2018). She has examined theses (4) and reviewed papers for the American Naturalist (3), Animal Behaviour (1), Ardea (1), the Auk (1), Current Biology (1), Ecology (2), Ecology Letters (3), Evolution (4), Evolutionary Ecology (1), Functional Ecology (2), Ibis (2), Journal of Animal Ecology (13), Journal of Ornithology (14), Methods in Ecology and Evolution (1), Oecologia (2), Oikos (2), PLoS ONE (1), Proceedings of the Royal Society B (11) and Seabirds (1). She has also reviewed grants for the European Research Council (1), UK Biotechnology and Biological Sciences Research Council (2) and Natural Environment Research Council (1), the Polish National Science Centre (1) and the Netherlands Organisation for Scientific Research (1). She holds licences for animal experimentation in Germany, the Netherlands and the UK and a ringing permit in Germany. She acts as an Animal Welfare Officer within the Institute of Avian Research. Her statistical skills include mixed models, mark-recapture survival analyses and quantitative genetic modelling using MLwiN, E-surge and R. She has organised/organises seminars for the Edward Grey Institute and Institute of Avian Research, has co-organised a symposium on 'Longitudinal studies of senescence' for the Benelux Congress of Zoology (2009), a Waterbird Society Meeting (2013) and a workshop on 'Causes and consequences of inclusive inheritance' (2019) and is currently organising a symposium on 'The evolutionary ecology of avian senescence: patterns, processes and the prices paid' for the International Ornithological Conference (2022). She teaches life-history evolution and a fieldcourse at the University of Oldenburg and has supervised/supervises the projects of 4 PhD students, 16 Msc students and 6 Bsc students. She strongly believes that scientists (and biologists in particular) should share their fascination for, and developing insights in, the natural world with a wide audience. With her team members, she therefore provides public tours and gives public talks (e.g. Science Pub, Science Slam). She is also collaborating with the city of Wilhelmshaven to establish a museum at her field site, maintains an academic Twitter account (@CommonTerns), participates in interviews for radio items and newspaper articles, and contributes to television programmes. Since 2019, she is deputy chair of the Nordwest-deutschen Universitätsgesellschaft and since 2020, she is on the extended board of the Marschenrat, co-organising local outreach events.
