Biography

Claus Rüffler is a theoretical evolutionary ecologist interested in the evolution and maintenance of phenotypic diversity in populations. He focuses particularly on the role of ecological interactions in driving the evolution of diversity. His research explores how phenotypic diversity results from genetic diversity and the interactions between the genotype-phenotype map and the environment. Utilizing mathematical models, Rüffler aims to understand the ecological conditions and genetic developmental constraints that favor alternative modes of phenotype determination. Additionally, he is interested in the origin of organismal complexity driven by the evolution of division of labor, considering that organisms consist of modules at various levels of organization, including genes, cells, segments, and individuals of clonal colonies, with each module fulfilling specialized functions.
