Ilkka Hanski

2000 Balzan Prize for Ecological Sciences

For his outstanding contributions to population and community ecology. His work has profoundly influenced our understanding of how populations in nature persist and how conservation policy of endangered species should be implemented.

Ilkka Hanski, born in Finland, on 14 February 1953 (†2016), is a Finnish citizen.
MSc (1976) at the University of Helsinki and DPhil (1979) at Oxford University.

Professor of Zoology (Animal Ecology) (since 1993) at the University of Helsinki, currently (1996-2001) Research Professor of the Academy of Finland.

Director of the Metapopulation Research Group, which has been chosen as a centre-of-excellence in research by the Academy of Finland for the period 2000-2005.

He has taken part in and continues to contribute to the work of the international scientific community, being a member of scientific councils, institutes and overseas societies, and advancing European-wide research in a large training network, which he coordinates and which involves seven other laboratories in as many European countries.

Among his honours and awards: 1999 Prize in Terrestrial Ecology, International Ecology Institute (ECI); President’s Gold Medal, The British Ecological Society (1999); member of the Academia Europaea (1998).

Currently associate editor or member of the editorial board of eight international journals.
