From 2015 to 2018, I did my PhD of computer vision for pest detection on crops at the University of South Australia. In 2018, I joined The Plant Accelerator, University of Adelaide as a post-doctoral researcher and spent two years in using hyperspectral images to estimate nitrogen content in wheat. I am currently working as a research fellow in The Plant Accelerator and my research interests include hyperspectral- and 3D-based plant phenotyping, computer vision, machine learning and deep learning in agriculture, optical sensing system design, bio-inspired machine vision system, bird vision, insect vision, high-dimensional colour space,  image processing, 3D model reconstruction and object recognition.
