Jesper Hoffmeyer is an associate professor at the Institute of Molecular Biology and Physiology (IMBP) at the University of Copenhagen who works primarily in the area of theoretical biology. After early research on genetic and biochemical regulation of purine nucleoside biosynthesis, he focused on the history of science and technology, and then, in 1988, established the Biosemiotics Group at the IMBP, which studies living systems from the perspective of sign theory. He is a graduate of the University of Copenhagen, where he earned a master’s degree in biochemistry in 1967, before pursuing post-graduate studies at the Collège de France on a science fellowship. Dr. Hoffmeyer began his teaching career in 1968 as an assistant professor at the University of Copenhagen’s Institute for Biological Chemistry, which he subsequently headed for two years. He was named to his present position in 1972. The University of Aarhus awarded him a doctorate in philosophy in 2005 in recognition of his pioneering contributions to the field of biosemiotics, and he is also the recipient of the 1985 Poul Henningsen Award, the 1991 Mouton d’Or Award for an article examining the semiotic metaphor in biology, and a Thomas Sebeok Fellowship awarded by the Semiotic Society of America on the occasion of its 25^th annual meeting in 2000. The current president of the International Society for Biosemiotic Studies, he serves, in addition, as a member of the governing boards of the Nordic Association for Semiotic Studies, SEE (The Virtual Institute of Semiosis, Evolution, and Energy), and the University of Copenhagen’s Centre for Ethics and Law. He is the editor of the Journal of Biosemiotics and a member of the editorial boards of Cosmos and History: The Journal of Natural and Social Philosophy and of Cybernetics & Human Knowledge. Dr. Hoffmeyer is the author of numerous articles published in scientific journals and eight books in Danish, including, En snegl på vejen: Betydningens naturhistorie (1993), which was issued in English by Indiana University Press as Signs of Meaning in the Universe (1996), and, most recently, Biosemiotik, which was published by Ries, Forlag, København in 2005.
