Nick’s work at NIAB focuses on using plant breeding to improve the sustainability and productivity of crops in a range of management systems. His PhD project investigates the genetic architecture of milling and baking, as well as nutritional quality, and how these traits can be predicted. This work uses various quantitative genetics approaches including QTL mapping using a MAGIC population and genomic prediction models to incorporate GxE interactions. Nick has been at NIAB since 2015, prior to starting his PhD in 2018, where he worked on developing the 16-founder MAGIC Diverse wheat mapping population and the NIAB pedigree resource. He also maintains an interest in crop breeding for low-input farming systems.
