Isabelle Schön
Senior Scientist
Aquatic & Terrestrial Ecology (ATECO)
Natural Environment
Isa Schön is a senior evolutionary biologist and molecular ecologist with over 30 years of expertise in studying the paradox of sex, speciation, and adaptations to changing environments. She uses molecular and genomic tools to investigate these fundamental questions, focusing on non-marine ostracods and marine amphipods as model organisms.
Function
Dr. Schön leads the Freshwater Biology Team at RBINS and has coordinated or participated in over 20 (inter-) national research projects. She served as Belgian PI for the Marie Curie RTN SexAsex and coordinated the RECTO project, including 6 partner institutions. Her research remains at the forefront of scientific developments, and has evolved from traditional genetics to cutting-edge genomics.
Dr. Schön works on non-marine ostracods and Antarctic marine invertebrates, studying asexual reproduction, speciation and the potential of transposons for adaptations. She currently supervises six PhD students, serves as RBINS polar liaison and as guest professor at the Hasselt University.

Area of Expertise
Dr. Schön has extensive expertise in genetic and genomic methods, from laboratory procedures to phylogenetic and population genetic analyses and bioinformatics. She specializes in developing non-model organisms, such as ostracods and amphipods, and continues expanding her molecular toolkit to include high-throughput environmental DNA and metabarcoding techniques.
Her research spans diverse ecosystems worldwide—from ancient Lakes Tanganyika and Baikal to the Southern Ocean, North Sea, and freshwater bodies across Europe, Australia, and USA.
Dr. Schön has authored over 110 peer-reviewed publications and 200+ additional publications. She has supervised multiple postdoctoral researchers, seven PhD students and more than 30 Master's and Bachelor's students.
External activities
Dr. Schön has served as Editor-in-Chief of the Belgian Journal of Zoology since 2009 and is a founding member of Peer Community In Zoology. She is a board member and past president of the Royal Belgian Zoological Society.
Committed to advancing women in science, Dr. Schön co-founded and served as president of BeWiSe, the Belgian network for Women in Science, contributing to building more inclusive scientific communities. She regularly serves as reviewer for scientific journals and as evaluator for research funding proposals.

Professional Experience
Dr. Schön exemplifies European scientific mobility. She completed her studies and PhD at Philipps University Marburg (Germany), where she served as assistant for Terrestrial Ecology, followed by postdoctoral positions at the University of Leeds (UK) and RBINS (Belgium). She has been awarded prestigious fellowships from the Studienstiftung des Deutschen Volkes (Germany) and the EU Marie Curie Programme.
Her international experience includes multiple research stays in Australia, at the Marine Biological Laboratory in Woods Hole, Massachusetts, USA (where she was awarded the Whitman Fellowship multiple times), and at the University of Gdańsk, Poland. This diverse international background has enriched her scientific perspective and fostered extensive collaborative networks worldwide.
