PETRA welcomes two new Principals to our Team!
Dr Zeljka Pokrajcic joins PETRA as a Principal. Zeljka is a mineral processing professional with 20 years’ experience in the mineral industry globally. She has experience in the commissioning, operation and optimisation of comminution and separation circuits. She holds a PhD in the design of energy efficient comminution circuits and was awarded the international TMS prize for her work. Zeljka is also a founding Director of CEEC International, a global not-for-profit group aimed at increasing awareness around energy efficiency in comminution. With such a stellar track record in comminution efficiency, Zeljka is the perfect fit to run our LABYRINTH® blast preconditioning and big-data mine-to-mill projects. With Zeljka’s expertise, we are now able to very efficiently understand any type of plant data, and very quickly get stuck into extracting value from our clients’ data assets!
Dr Alan Offer has joined us as Principal Mathematician. Alan has a great passion for all aspects of mathematics and its application across a wide range of fields and industries. His previous data analytics roles include mining, meteorology, transport, ecology, programming and biology. As a highly proficient R and Python programmer he is working with us to develop innovative and creative workflows. Since joining PETRA only a few weeks ago, Alan has single-handedly increased our FORESTALL workflow productivity by 30%, reducing our project turnaround time from about 6 weeks to about 4 weeks. Alan is the AMOC State Director (Queensland) and member of the Senior Problems committee for the Australian Mathematics Trust.
