The Konrad Lorenz Institute for Evolution and Cognition Research (KLI) is an international center for advanced studies in the life and sustainability sciences. It is a "Home to Theory that Matters" that supports the articulation, analysis, and integration of theories in biology and the sustainability sciences, exploring their wider scientific, cultural, and social significance. The institute is located in Klosterneuburg, near Vienna, Austria. Until 2013, the institute was located in the family mansion of the Nobel Laureate Konrad Lorenz in Altenberg. Lorenz' work laid the foundation for an evolutionary approach to mind and cognition. The institute unites fellows, visiting scholars, students, and external faculty. Through a lecture and seminar series, the KLI also offers a platform for the critical public discussion of current themes in the biosciences. Founded in 1990 by Rupert Riedl, followed by Gerd B. Müller as president of the institute, the KLI is funded by a private trust and receives additional support from the Province of Lower Austria. The institute has close ties with many of the higher education institutions in Vienna and Lower Austria as well as with a number of international institutions with similar aims. Activities The KLI supports theoretical research primarily in the areas of evolutionary developmental biology, evolutionary cognitive science, and sustainability science that welcome an evolutionary approach. This is accomplished by providing fellowships to graduate students, postdocs, and visiting scientists for research projects they have proposed. In addition, the KLI organizes lecture series, organizes symposia, and hosts workshops. The KLI provides an extensive internet database for literature in theoretical biology and related fields. Together with Springer Science+Business Media, it publishes the journal Biological Theory. Fellows Fellows are scientists and scholars (e.g., in the biological and social sciences and in the humanities) who come to the KLI to work on a project corresponding to the aims of the institute. The KLI primarily supports theoretical research in the fields of evolutionary developmental biology, evolutionary cognitive science, and the sustainability sciences, but KLI is open to other related and interdisciplinary fields of research. Past and current fellows have come from a large number of countries, and have been trained in various disciplines within the social and natural sciences, and humanities. KLI Lab / KLI Colloquia The KLI Lab provides a flexible format for informal talks and peer discussion, primarily aimed at presenting work in progress related to the institute's aims. The KLI Colloquia are regular
