I am a quantitative geneticist working on the genetic analysis of complex traits in crops. My research interests include QTL mapping in multi-parent populations and association mapping, with a focus on genetic interactions and multi-trait analyses, as well as the use of genomics data. I have a strong interest in modern breeding technologies particularly genomic prediction, with a focus on the incorporation of GxE interactions into prediction models. I also teach courses in applied quantitative and population genetics for plant breeders.
