I am in the Statistics Team, AgResearch group of the Bioeconmy Research Institute, New Zealand. My research is in Animal Science, Genetics and Statistics. Current projects are genomic selection in sheep, deer and other species, analysis methods for genotyping by sequencing data, epigenetics of livestock and climate adaptation in finfish.
