Researcher biography
Currently working as a Senior Research Officer/Lab manager of the Geomechanics Engineering Centre lab at UQ. Currently in projects related to instrumentation and long term monitoring of drying and wetting cycles of large scale columns with tailings or soil. Over 5 years of experience testing mechanical, physical and chemical properties of soil and tailings. Specific experiences in consolidation, direct shear, triaxial, SWCC, sensor instrumentation and characterization tests.
PhD student at the school of Civil Engineering
