Research interests 

  • Agro-environmental science
  • Soil science
  • Visual evaluation of soil structure
  • Soil quality and health
  • Soil organic matter

I am a soil scientist. My current research focuses on agricultural soil systems under different management activities, assessing soil greenhouse gas emissions and mitigation, soil structure and quality, carbon storage and stability and nutrient dynamics. I completed my PhD in Environmental Geochemistry at the University of Edinburgh in 2006.

Selected research projects:

  • CREW ‘Pathways of Diffuse Pollution to the Water Environment’
    State of knowledge review and communicating best practice.
  • BBSRC ‘Sustainable economic and ecological grazing systems - learning from innovative practitioners’
    Evaluation of the agronomic and social impacts of the Pasture for Life certified approach to grazing management and its potential as the basis of a sustainable GB-wide system.

  • AHDB Soil Biology and Soil Health Partnership
    Measuring soil health and soil biology and the development of a soil health scorecard.
  • Scottish Government Rural Affairs, Food and Environment: Theme 2 ‘Productive and Sustainable Land Management and Rural Economies’
    WPs 2.3.4 (Sustainable soil and water management), 2.3.5 (Improving existing greenhouse gas reduction measures (lead for objective 3)) and 2.3.8 (Alternative approaches to sustainable land management).
  • CREW ‘Valuing Your Soils’
    Practical guidance brochures, videos and awareness raising workshops for Scottish farmers (available from http://www.sruc.ac.uk/homepage/678/soil_and_nutrients).

  • AHDB Dairy ‘Grassland soil assessment tool’
    ​​​​​​​
    Production of a pocketbook to help farmers maintain healthy grassland soils (available from https://dairy.ahdb.org.uk/technical-information/grassland-management/healthy-grassland-soils/#.W2Wflf6Wzcs).

Teaching

I have a Postgraduate Certificate in University Teaching.

Postgraduate teaching: I am a lecturer, core course (Atmospheric Quality and Global Change) co-ordinator, moderator, personal tutor and MSc dissertation project supervisor for SRUC and University of Edinburgh MSc/PG dip programmes. I deliver teaching mainly for the 'Environmental Protection and Management' and 'Soils and Sustainability' programmes.

Undergraduate teaching: I am a lecturer for the University of Edinburgh’s Global Academy Agricultural Science BSc programmes and a dissertation research supervisor for various SRUC BSc (hons) students.
