Malcolm's work focuses on the ecology, conservation and management of island avian biodiversity.

By combining research disciplines (primarily population and movement ecology) we are able to identify threats, explore the effectiveness of potential conservation actions and provide guidance to inform management actions in both terrestrial and marine systems.

Current research focuses on island systems in the Indian Ocean, in collaboration with local government, academic and conservation NGO partners. This includes long-term studies (>30 years), a range of species-specific recovery programs, for example the endangered Mauritius kestrels, and the restoration of important seabird islands and protection of their surrounding marine environments.
