ChatGPT: Hans-Hermann Thulke is a German mathematical biologist whose work bridges ecological modelling, disease ecology, and environmental health. Based at the Helmholtz Centre for Environmental Research (UFZ) in Leipzig, he develops spatially explicit models to understand and manage infectious diseases in wildlife, particularly African and Classical Swine Fever in wild boar. His research extends to plant health, bee health, pest management, and plant-environment interactions, contributing to risk assessments for invasive species, pollinator decline, and emerging plant pathogens. Thulke plays an active role in European Food Safety Authority (EFSA) panels, advising on integrated strategies for disease control across species and ecosystems. He is also involved in modelling the effects of stressors on pollinators and investigating plant intelligence within ecological networks. His work exemplifies the “One Health” approach, uniting animal, plant, and environmental health through applied, systems-based modelling that informs real-world policy and conservation strategies at both national and European levels.
