PhD position in plant-insect coadaptation A PhD position in plant-insect coadaptation is available by 1st of January 2026 in my group at the Department of Systematic and Evolutionary Botany, University of Z�rich, for a period of four years. The position is to study patterns and mechanisms of coevolution between a plant, wild radish (Raphanus raphanistrum) and its pollinating-herbivore, Pieris rapae. In this project, field work and greenhouse experiments will be combined with lab-based analyses to study the fitness impacts of Raphanus and Pieris on each other, and investigate patterns of trait matching between plant and insect in natural populations in Switzerland. I am looking for a highly motivated PhD candidate to join my team working on evolutionary question in the context of plant-insect interactions. I offer a vibrant, collaborative work environment and high-quality supervision. Several of my past PhD students have published as first authors in the highest-ranking journals such as Science, Nature Communications, New Phytologist, Functional Ecology, etc.; many have consecutively attained PostDoc positions at renowned academic institutions. You should have a Master (or comparable) degree in any field of biology and a thorough interest in evolutionary biology; proficiency in English, both orally and written, is also required. Prior experience in working with plants and/or insects, genomics analyses, and scientific publishing as well as knowledge of German is an advantage. You should like to work in the field and have some basic knowledge of plant and insect taxonomy. Our department is located in the university botanical gardens and houses modern molecular and ecological labs, including greenhouses and climate chambers for plant cultivation. The University of Z�rich has a broad research coverage of organismal and molecular biology, and several research groups work on evolutionary topics (www.lifescience-zurich.ch). If you are interested in the job, please send me by e-mail (florian.schiestl@systbot.uzh.ch) a letter describing your motivation, CV, copy of degrees, publications (manuscripts), and e-mail addresses of two academic referees, by 1st of December 2025 (the job will remain open until filled). Please send all documents in a single file. If you have any further questions, don`t hesitate to contact me. "Florian P.
