Theoretical ecologist Matthew Holden and conservation economist Katrina Davis are postdoctoral research fellows at the Centre of Excellence for Environmental Decisions at the University of Queensland, Australia.

Dr. Holden is especially interested in determining the most cost-effective management actions when conservation benefits depend on how humans modify their behavior in response to policy. Dr. Davis's current research examines how to integrate expert and stakeholder preferences for marine ecological features by incorporating non-market valuation into marine spatial optimization.
