Professor Jim Monaghan

BSc, PhD

Professor of Crop Science / Director of the Fresh Produce Research Centre

Teaching Duties

  • Fresh produce production
  • Post harvest technology
  • Horticultural production systems
  • Food safety in the production of fresh produce
  • QA systems and their role in the supply chain

Sustainable School of Food and Farming

I am lead contact for the areas of fresh produce and potato crops at HAU.  In this role I co-ordinate interaction between relevant academics and commercial growers involved in the network School of Sustainable Food and Farming

Research projects

My research work is carried out at the Fresh Produce Research Centre:

My work is in the area of phenotyping and crop production systems, both pre and post harvest.

  • Vegetable Genetic Improvement Network - VEGIN (Defra funding)

This work is joint with University of Warwick and is identifying genetic traits that are linked to stress resilience in leafy and root vegetables. The work at HAU focussing on abiotic stress resilience is being done by Dr Olivia Cousins

  •  Tuberscan (Innovate funding)

This is a project led by B-Hive Innovations, to develop ground penetrating radar, underground scans and AI to monitor potato crops and identify when they are ready to harvest.  

  • Automation harvesting of whole-head iceberg lettuce (Innovate funding).

This project is lead by Grimme UK and involves the AgriEpicentre, UWE, IDS imaging, PDM and G's and is developing a prototype system for automated harvesting of wholehead lettuce.

  • Commercial trials

I have recently managed commercial trials for a number of companies including PepsiCo and G's.
