Research interests

My research focuses on the use of molecular markers to determine the loci responsible for variation in quantitative traits (quantitative trait loci or QTL) with the ultimate purpose being to understand the nature of genetic variation underlying complex traits. I am particularly interested in the development and application of statistical methods to detect and characterise QTL that are segregating in outbred populations (of plants, animals or humans).
