Kai-Hsiu Chen

Dr. Kai-Hsiu Chen is a Researcher in the Department of Ecology and Evolution at the University of Lausanne. Affiliated with the Pannell group, his research focuses on the ecology and evolution of plant mating systems, sexual strategies, and pollination biology. He holds a post-doctoral position and has conducted PhD research on sex allocation strategies in alpine plants such as Anemone alpina and Mercurialis annua.

His work investigates trade-offs between growth, survival, and reproduction in plants, effects of herbivory on floral traits, and pollinator-driven selection pressures. Key topics include fitness consequences of sex allocation, resource reallocation dynamics, and reproductive success under environmental constraints. His research spans both experimental and theoretical approaches, often integrating field studies with population-level analyses.

Dr. Chen’s studies frequently involve alpine and subtropical ecosystems, exploring how plants adapt to pollination syndromes, phenological timing, and antagonistic interactions. He maintains a personal webpage (https://chenkaihsiu.wixsite.com/kaihsiuchen), and is based in Lausanne at Office 4310. No scientific awards are explicitly mentioned in the provided information.

His research has contributed to understanding dioecy evolution, floral trait selection, and the role of unisexual flowers in resolving genetic conflicts. While no advising roles or grants are listed, his work is part of broader efforts to elucidate plant reproductive ecology and evolutionary mechanisms. He collaborates within the Pannell group, focusing on plant-pollinator interactions and ecological adaptation strategies.
