Dr Julian Taylor

Julian is a Senior Research Fellow in the University of Adelaide

Dr. Julian Taylor is a Senior Research Fellow in the Biometry Hub located at the Waite Agricultural Precinct of the University of Adelaide. He is also a Program Leader for the southern node of the Statistics for the Grains Industry project, a Grains Research and Development Corporation (GRDC) funded initiative to provide biometrical research support for southern regional GRDC projects.

Dr. Taylors research is based on the development of statistical methodology and models along with their computational implementation for use in the analysis of plant breeding experiments. Much of this research is multi-disciplinary  and highly collaborative with plant researchers in the university as well across other scientific communities involved in plant breeding research. A substantial focus of the research is in the competitive research area of statistical genetics in crop agriculture. This includes the theoretical and computational research development of gene-trait association modelling such as quantitative trait loci (QTL) analysis and genome wide association analyses.

Additionally, Dr. Taylor is the co-author and maintainer of statistical software packages R/wgaim and R/ASMap written in the open source R statistical computing environment. These packages have provided plant research staff in the university with highly efficient tools for the genetic analysis of their experiments and continue to play an important role in providing research outcomes for their projects.
