Dr Karina Jorge Barbosa

Postdoctoral Research Fellow

JKMRC

k.barbosa@uq.edu.au

Karina graduated with a Bachelor of Mining Engineer and completed a Master in Geotechnical Engineering, both in Brazil.

Dr Karina Jorge Barbosa is an early career researcher, who was awarded her PhD from The University of Queensland's School of Earth and Environmental Sciences, focusing on the alternative methods for geomechanical characterisation of sub-bituminous coal.

Karina has eight years of experience in geotechnical and rock engineering in multiple-commodity, including soft and hard rock mining environments. She worked on the application of geomechanics and rock mechanics principles to open pit slope engineering and underground mining projects and operations. Karina is very familiar with intact rock and rock-mass characterisation techniques and is competent in carrying out numerical modelling of mine designs and optimisation of mine layouts.

Karina joined the JKMRC with a geotechnical background and a strong desire to further explore ore characterisation. She is keen to implement some fundamental understandings of rock behaviour (shape, size and texture), explored in her research, for offering solutions to mineral processing and innovations for mineral comminution.
