Eveliina Hanski
Early-Career Fellow 2025–2026

Eveliina Hanski is a researcher working at the intersection of microbial ecology and ageing. Her work investigates how the gut microbiome–a community of microbes living in the gut–develops in early life, and how these early dynamics influence health later on. At the Collegium, she will investigate whether disruptions to the gut microbiome in early life can alter the pace of biological ageing.

Originally from Finland, Eveliina earned her PhD at the University of Oxford (UK) in 2023, where she studied host-microbiome interactions. Before joining the Collegium, she held postdoctoral positions at both the University of Oxford (UK) and the University of Helsinki (FI). Eveliina works across diverse study systems, integrating ecological, molecular, and biomedical approaches. Alongside her research, she has tutored biology undergraduates at the University of Oxford and contributed to public outreach, including delivering an invited talk at a National Geographic event.
