I am a final-year PhD candidate at the University of New South Wales, Sydney, Australia, affiliated with the ARC Training Centre in Data Analytics for Resources and Environment (DARE).

I am supervised by Dr. Rohitash Chandra, Dr. Sahani Pathiraja, and Professor Lucy Marshall. My research focuses on the synergy of process-based hydrological models with machine learning to advance environmental process modeling. I have developed hybrid and Bayesian deep learning approaches for rainfall–runoff modeling, flood forecasting, cyclone prediction, and groundwater flow emulation.

Alongside my PhD, I worked as a Climate Science Support Officer at the Bureau of Meteorology, implementing multivariate bias correction for climate projections and modernizing legacy workflows. Previously, I held roles as a Data Scientist and Machine Learning Engineer, designing and deploying scalable ML systems across various domains.
