is a theoretical biologist and historian of science. His undergraduate training was in zoology, philosophy and mathematics at the University of Vienna (Austria) and his graduate training was in biology at Yale and in History/History of Science at Princeton. His research covers three distinct yet overlapping areas. His work in theoretical biology is focused on conceptual and mathematical issues, such as the problem of defining biological characters in development and evolution, the homology problem, and the theory of epistatic and epigenetic effects. In evolutionary developmental biology Dr Laubichler is interested in problems of phenotypic evolution focusing on social insects as a model system. His ultimate interest is to contribute to an understanding of evolutionary innovations through the integration of genetic, developmental, physiological, and behavioral perspectives. In History of Biology Dr. Laubichler specializes on 19th and 20th century biology. He is especially interested in the history of theoretical biology and the history of embryology and developmental biology.
