• Led innovative research projects focused on optimising fibre-reinforced shotcrete for underground mining, resulting in a new paradigm for enhanced ground support performance in shotcrete applications.
• Performed advanced 3D Distinct Element Modelling (DEM) using 3DEC to investigate the interactions between shotcrete, rock bolts, and rock in mechanised underground mine drives. This research opened new avenues for ground support optimisation, based on the concept of tunnel rock surface cavity filling.
• Conducted comprehensive literature reviews by analyzing existing research to identify gaps and inform new studies.
• Developed research proposals for securing funding, enhancing project visibility and support.
• Designed and executed test experiments to test the cavity filling hypothetical support mechanisms, collaborating with multidisciplinary teams to ensure successful implementation.
• Developed risk management protocols to guarantee the safe execution of test experiments.
• Managed project timelines and costs to ensure timely delivery and operational efficiency.
• Currently a PhD candidate at the University of Western Australia, researching on "Enhancing the Efficacy of Fibre Reinforced Shotcrete Ground Support Systems using Rock Surface Cavity Filling."
• Presented research findings at numerous industry sponsor meetings, elevating the organisation's profile and fostering key partnerships within the mining community.
• Authored research papers on the effects of rock surface cavity filling in enhancing the efficacy of fibre-reinforced shotcrete in underground mining drives

Conducted background research on fibre-reinforced shotcrete in mining.

Performed numerical modelling in FLAC3D to evaluate stress paths around a typical long-hole open stoping mining layout with post-fill.

• Participated in geotechnical feasibility studies for both open-pit and underground mining.
• Led advanced numerical modelling projects for large open-pit mines.
• Performed various geotechnical analyses to inform design and safety decisions.
• Presented design recommendations and study results to clients.
• Managed multiple projects to ensure timely and cost-effective delivery.
• Provided training and mentorship to junior geotechnical engineers.
