SPEAKER BIOGRAPHY

Prof. Graham King – Southern Cross University, Australia

Graham King is Director of Plant Science at Southern Cross University. He graduated from the University of Manchester and was awarded his PhD from the University of London. With over 25 years’ experience leading research on crop plant genetics and genomics, he has made major progress in quantitative genetics of complex traits and characterising genetic diversity in domesticated plants. Graham’s current area of interest is understanding the molecular basis of crop plasticity and epigenetics.
