Research Interests

My main interests are in the fields of ecology, and of the use of scientific evidence in order to support and underpin policy and management decision making. I am director of the Centre for Evidence Based Agriculture http://www.harper-adams.ac.uk/initiatives/centre-evidence-based-agriculture a reviewing, training and co-ordinating hub for the collation and synthesis of agri-food evidence.   I am also on the editorial board for Environmental Evidence, a journal for the publication of systematic reviews and evidence syntheses on the effectiveness of environmental management interventions and on the impact of human activities on the environment.

Research fields:

Agricultural Ecology and Biodiversity, Invasive Species, Evidence synthesis for environmental and agricultural decision making, Systematic Review, Systematic Mapping, Ecological Policy, Dissemination and use of research information.
