Our research integrates economics, ecology, and mathematical methods to understand the management of biological natural resources such as forests, fish, or reindeer. This has created a dialogue between existing scientific traditions and new discoveries that is realized by transferring knowledge between various fields. In proceeding toward new directions, we are guided by cross-disciplinarity and the requirements of sound theoretical basis, mathematics, detailed empirical realism, and computational methods. This enables harsh, progressive, and critical reflection of existing science, policy, and practice.
