Research
We are passionate about understanding how and why animals behave and function the way they do—both in pristine environments and in those shaped by human activity. A key theme in our research is time: nature is dynamic, and biological timing influences nearly every aspect of life. We investigate how animals’ responses to environmental change vary with time—be it time of day, season, or life stage—and how disruptions ripple through individuals, populations, and ecosystems. Our studies combine controlled lab experiments with approaches that incorporate ecological realism (e.g., mesocosms, field studies) and economic realism (e.g., animal production systems), spanning a broad range of (mostly aquatic) species and environmental contexts.
Some research themes:
How do animals behave in a changing world?
We study how animals adjust their behaviour in response to environmental change—whether caused by chemical pollution, plastics, artificial light at night, or other stressors. We aim to understand both the causes and consequences of these changes, linking individual responses to population- and community-level outcomes. This work helps refine ecological theory and supports more effective environmental regulation.
How do species interact under stress?
Animals live in networks of interactions—with partners, competitors, parasites, predators, and prey. We explore how environmental change reshapes these interactions, including symbioses like those between jellyfish and dinoflagellates. These relationships could amplify or buffer the effects of stressors—an area that is still mostly unknown terrain.
How do animals live in temporary habitats?
We investigate how organisms interact with each other and their environment in surface waters, with a special focus on temporary ponds—biodiversity hotspots that are often overlooked. Our research centres on the ecology and evolution of annual killifish and large branchiopods in (south)east Africa. These dynamic habitats offer unique opportunities to study ecological questions and inform conservation and sustainable management.
How do animals respond to emerging pollutants?
Ecosystems today face increasing chemical pressure—from pharmaceutical residues to pesticides and microplastics. We assess how these pollutants affect animal health and behaviour, often at low concentrations and in complex mixtures. Our work focuses not just on the effects themselves, but also on how best to study them—bridging the gap between lab-based ecotoxicology and ecological realism to support safer chemical management.
How do we keep aquaculture sustainable and animal-friendly?
We apply ecological and behavioural knowledge to improve the sustainability of aquatic animal production. This means reducing environmental impact, enhancing animal welfare, and developing evidence-based husbandry practices. Working closely with pilot-scale facilities, we aim to translate fundamental research into practical solutions for greener aquaculture.
How should we do science?
We reflect on how science is conducted, shared, and rewarded. Our work in meta-science focuses on increasing rigour, transparency, and inclusivity in ecological and ecotoxicological research. From preregistration and open data to fair authorship practices, we champion a research culture that is not only excellent but also equitable and trustworthy.
