Current research interests

  • Root trait responses to soil physical conditions, including changes in border cell production, exudate production, changes in root meristem and overall root structure.  
  • Variation in responses to physical constraints between barley mutants and cultivars.
  • Utilisation of confocal microscopy and computer vision techniques to develop tools for measuring cell expansion and root elongation.

Past research

  • Movement, replication and suppression of Tobacco mosaic virus and Tobacco rattle virus in tobacco and Arabidopsis. Utilisation of Tobacco rattle virus as a vector for inducing gene silencing of endogenous root development genes (Mylnefield Research Services).
  • Growth and development effects of cell wall carbohydrates (University College London)

The James Hutton Research Institute is the result of the merger in April 2011 of MLURI and SCRI. This merger formed a new powerhouse for research into food, land use, and climate change.
