About Me

I am a postdoctoral researcher at the University of Sydney, and a visiting scientist at the Commonwealth Scientific and Industrial Research Organisation (CSIRO). I am interested in using data-driven methods to better understand fine-scale land-atmosphere interactions in the context of climate extremes (e.g., drought and heatwave). My PhD explored the role of land surface temperature in improving spatiotemporal predictability of soil moisture-related agricultural drought. I also worked on an ANU-CSIRO Himawari-8 project that aimed at developing best-practice geostationary data products for enhanced sub-daily monitoring of Australia’s ecosystems.

📚 My Research

I am currently working on the development of mechanism-driven deep learning model to enable enhanced spatial agricultural modelling at the USYD Precision Agriculture Lab. I am also involved in a few industry-aligned projects focusing on interdisciplinary challenges in agricultural innovation and climate science, leveraging statistical methodologies and high-performance computing (HPC) resources.

Previously, I developed a variant of a spatiotemporal fusion algorithm to enhance the accuracy of downscaled land surface temperature (LST) data, alongside which I released a benchmark dataset to support future algorithmic refinements.

I also contributed to a Himawari-8 project that aimed at developing geostationary data products for enhanced sub-daily monitoring of Australia’s ecosystems, where I was responsible for the development of an LST product.
