Guilhem Sommeria-Klein

Guilhem Sommeria-Klein is a Research Fellow in the Department of Computing at the University of Turku, Finland, holding an Academy of Finland postdoctoral research fellowship focused on probabilistic modeling for microbial ecology. He teaches the Statistical and Probabilistic Programming course and contributes to the Turku Data Science Group under Professor Leo Lahti.

His academic training spans disciplines with a Master's degree in Physics and a PhD in Ecology from Toulouse, France, where he conducted theoretical modeling, field DNA sampling, and statistical analysis of ecological communities.

Dr. Sommeria-Klein develops probabilistic frameworks to integrate classical ecological theory with microbial data science, advancing understanding of community assembly and dynamics across host-associated microbiota, soil ecosystems, and ocean plankton. His interdisciplinary methodology bridges mechanistic models from evolution with tailored statistical approaches for high-dimensional omic datasets.

Recent publications (2021-2025) reveal consistent application of spatial and phylogenetic modeling to microbiome systems, with emphasis on ocean plankton biogeography (Tara Oceans project), gut microbiota evolution in vertebrates, and antibiotic resistome dynamics in human cohorts like FINRISK.

No scientific awards are documented in the provided materials.

Supported by his Academy of Finland fellowship, he actively collaborates within the Turku Data Science Group on grant-funded research while mentoring through course instruction. His work demonstrates strong integration of theoretical ecology with computational data science across diverse biological scales.

His primary research environment is the Turku Data Science Group, with significant prior contributions to the international Tara Oceans consortium for marine microbial studies.
