Education

Pierre-Olivier Cheptou has a solid academic foundation rooted in evolutionary biology and ecology. He began his higher education at Montpellier University, where he earned a Master of Science (MSc) degree in Evolutionary Biology and Ecology. Driven by a keen interest in population biology and ecological adaptation, he pursued doctoral research at the same institution. He completed his Ph.D. in Population Biology and Ecology at Montpellier University, producing work that laid the groundwork for his later research on seed dispersal and mating systems in plant populations. Further solidifying his academic leadership, Dr. Cheptou obtained his Habilitation à diriger des recherches (HDR), which is a prestigious post-doctoral qualification in France that certifies the ability to supervise doctoral research. This academic progression—from MSc to Ph.D. and HDR—demonstrates a consistent focus on evolutionary mechanisms, ecology, and adaptation, especially in relation to plant species in anthropogenic and natural environments. These credentials have not only positioned him to lead groundbreaking research but also to mentor graduate and doctoral students effectively, expanding the intellectual reach of his work through teaching and supervision at major European institutions.

Experience

Dr. Pierre-Olivier Cheptou has held a series of progressive and impactful roles throughout his professional career. Following his doctoral studies, he undertook a prestigious post-doctoral stay at McGill University in Montreal, Canada, in Dan Schoen’s lab. This international experience strengthened his collaborative networks and exposed him to advanced methods in population biology and genetics. He began his career with the French National Centre for Scientific Research (CNRS) as a CR2-level researcher at CEFE (Centre d’Écologie Fonctionnelle et Évolutive). He was promoted to CR1 and then to Directeur de Recherche 2 (DR2), reflecting his growing contributions and leadership in the field. Over the years, he has coordinated multiple national and international research projects, supervised numerous graduate students, and contributed to the development of CEFE’s research infrastructure. Notably, he served as the head of the “Dynamics and Adaptation of Plant Populations” group and as the scientific coordinator of the Labex CeMEB experimental platform. He has also taught at Montpellier University and was an Associate Professor at Université Libre de Bruxelles. These roles highlight his interdisciplinary expertise and significant impact on ecological research and education in France and beyond.

Research Interest

Pierre-Olivier Cheptou’s research interests lie at the intersection of evolutionary ecology, plant population biology, and urban ecology. He explores how plants adapt to human-altered environments, with a specific focus on seed dispersal mechanisms, mating systems, and eco-evolutionary feedbacks. A central theme in his research is understanding rapid evolutionary responses to urbanization, treating cities as active evolutionary arenas rather than ecological dead ends. His pioneering work on Crepis sancta demonstrated how urban landscapes influence natural selection and trait evolution. He is deeply interested in “resurrection ecology,” where seeds preserved over time are germinated to assess evolutionary changes across generations. His projects investigate the evolutionary consequences of pollinator decline, fragmentation, and habitat alteration on plant traits. Cheptou is also involved in integrating theoretical models with empirical data, extending metapopulation models and hidden Markov models to estimate seed dormancy and dispersal. These interests converge in a multidisciplinary framework that combines ecology, genetics, statistics, and conservation biology. By linking fundamental evolutionary theory with applied conservation and urban planning, his research contributes to both scientific advancement and practical biodiversity management. His ongoing commitment to interdisciplinary and international collaboration underscores his role as a thought leader in the field of urban evolutionary biology.

Research Skills

Dr. Cheptou brings a diverse and robust research skill set to the field of evolutionary ecology. He is highly proficient in field experimentation, statistical modeling, and evolutionary analysis, particularly in urban ecological contexts. One of his unique strengths lies in his ability to bridge empirical and theoretical approaches. His use of hidden Markov models to estimate traits such as seed dormancy and dispersal demonstrates his advanced statistical competencies. Additionally, he is skilled in genetic and ecological sampling techniques, enabling him to link phenotypic changes with underlying evolutionary drivers. His work involves the application of resurrection ecology methods, which require long-term seed storage, precise phenotyping, and temporal comparisons to measure evolutionary change. Cheptou also excels in interdisciplinary research design, combining concepts from ecology, population genetics, and landscape biology. He is adept at research coordination, having led multiple collaborative projects funded by institutions such as the NSF (USA), FRB, OFB, and the French Ministry of Higher Education and Research. His editorial and peer review activities for journals like Evolution, BMC Evolutionary Biology, American Naturalist, and New Phytologist further demonstrate his critical evaluation and communication skills. These competencies allow him to produce high-quality, high-impact research that informs both academic circles and public environmental policy.

Awards and Honors

Throughout his career, Pierre-Olivier Cheptou has been recognized for his innovative and impactful research through numerous grants and honors. He was the recipient of the Young Researcher ACI program grant for his pioneering work on urban plant populations. His leadership in the FRB research program on plant adaptation through resurrection ecology further positioned him at the forefront of ecological evolution studies. He also led the “Chercheurs d’avenir” project, supported by Région Languedoc-Roussillon, focusing on advancing metapopulation models in plant biology. Internationally, he was a key participant in the Nescent Working Group funded by the NSF (USA), exploring the evolutionary limits of Baker’s law. In recent years, he has secured funding for large-scale projects, including the ongoing “Resurrection Ecology in Agrostemma githago” and “Plant Adaptation in a Rural/Urban Gradient”, funded by OFB and Région Occitanie. He has served on evaluation panels for international funding bodies such as NSF, Israel Science Foundation, ERC, and Czech Science Foundation.
