Group Leader

Professor Alok Porwal

Alok is PhD in mineral exploration from Utrecht University, the Netherlands. He is an adjunct faculty at the Centre of Exploration Targeting, the University of Western Australia. His research interests include GIS-based Mineral prospectivity modelling, uranium, gold and nickel mineral systems, machine learning and artificial intelligence in geological studies, geologic remote sensing (terrestrial and planetary) and spectroscopy of geologic material.  He is one of world’s leading authorities on mineral prospectivity modelling and spatial data management and analysis. Basically an academic, he works very closely with the industry and has been involved in a large number of projects for mining industry in Australia, Africa and India.

He is on the editorial board of several international journals. He has guest edited two special issues of Ore Geology Reviews focussed on mineral prospectivity modelling, and currently editing a new special issue on geologic remote sensing. A prolific researcher, he has published over 60 highly cited papers in international journals. He and his group have developed a new knowledge-driven prospectivity modelling tool known as fuzzy interference system. He is also working on developing new technology for palaeochannel detection using remote sensing data.

In addition to his regular teaching, Alok conducts short-term courses and workshops on mineral prospectivity modelling for government agencies and industry in different countries.
