Background
Dr Landahl is an expert in mechanical properties of fruit and vegetables with extensive experience in non-destructive vibrational measurement systems, controlled atmosphere storage and standard destructive textural, biochemical and physiological testing of fresh produce. In addition to UKRI and industrially funded research work, she is also managing the operation and maintenance of key equipment in the PSL. She is providing training for staff, students and visitors on lab equipment and is involved in both teaching and student supervision. Finally, she is also the Health and Safety co-ordinator for Agrifood with a NEBOSH certificate.
Dr Landahl co-operated with the Cranfield team since 2007, when she completed her PhD at the K. U. Leuven Belgium, and then worked for the Biomimetics department at the University of Reading for three years. After that, she joined the Plant Science Laboratory (PSL) one of the best-equipped postharvest labs in the world.
Current activities
Development of a decision support tool to reduce asparagus tip breakdown in the UK:
To reduce food waste and losses, this project will seek to identify factors responsible for tip breakdown in asparagus, and create a decision tool to predict spears predisposed to the disorder before symptoms develop.
