Doctoral Researcher in Optimization of Mineral Resource Modelling Using Machine Learning Approaches

We at the University of Oulu work as part of the international science community to produce new scientific information and science-based solutions. We are committed to educate future pioneers to build a more sustainable, intelligent and humane world. Creating new, taking responsibility and succeeding together are values that build a strong foundation for all our actions. We offer a working environment where individuals can cultivate their skills, do meaningful work, and develop professionally. Our university’s several specialized research and service units enable extensive and diverse development and career opportunities for experts in various fields.

We are looking for a Doctoral Researcher for the Horizon Europe funded SEMACRET (Sustainable Exploration for Orthomagmatic (critical) raw materials in the EU: Charting the road to the green energy transition project. The SEMACRET consortium includes 16 partners from EU, UK, South Africa and is, coordinated by Oulu Mining School (OMS).

Open position

The PhD project includes working on optimizing mineral resource modelling using machine learning approaches. Reference sites include magmatic Ni-Cu-PGE-V-Ti deposits in Finland, Poland and Czech Republic.

Traditional resource modelling approaches include using a set of geostatistical techniques that in the end results estimate of grade distribution within given mineral deposit. Different type of interpolation methods are used (e.g. Kriging) to predict grade in unknown locations based on the adjacent measured known values. There are several possible human based errors during the mineral resource estimation workflow. Machine learning algorithms have developed drastically during the recent decades due to the increase in the computational power. The potential gain for using machine learning in the resource modelling is to reduce the human based errors, increase the automatization of the process, and result more accurate estimations of the grade within the ore domains.  The PhD is supervised by Dr. Jukka-Pekka Ranta (OMS) and Professor John Carranza (University of Free State, South Africa)

Qualification requirements

– M. Sc. degree in the relevant field. Ability to work in international research groups.

– Background on statistics or high motivation to learn to work with large geochemical datasets.

– Background in data science programming languages (e.g. R, python). Experience in mineral resource estimation or 3D modelling is seen as benefit.

We expect a highly motivated candidate with a master´s degree in geosciences, or in related subject. Master´s degree must have been completed by July 2022. The earliest starting date will be 1 August 2022.

We expect excellent spoken and written English skills as this is needed to work in multidisciplinary and international research groups.


What we offer

  • 24-months fully funded doctoral researcher position with 12 months/year salary payment.
  • You will become part of international research group including companies, universities and research organizations from Finland, United Kingdom, Poland, Czech Republic and South Africa.
  • You will receive support not only from your team and supervisor, but also from university´s wide variety of support services, so that you can excel in your studies and research / work.
  • In addition to modern research facilities, we offer you personnel benefits such as occupational healthcare, sports, culture and wellness benefits.
  • Flexible working hours (1612 hours/year)

Other benefits: The successful candidate will receive full benefits provided by the University of Oulu to university employees, including free time corresponding to holidays and free occupational health care services. The successful candidate will receive also benefits provided by the Finnish government to residents, for example possibility to obtain access to the national healthcare system, tax benefits for employees with children and high-quality affordable childcare services.

Postdoctoral Researcher position in Data Science: Multi-task learning in bioinformatics

The University of Oulu is an international scientific community, with approximately 16 000 students and 3 000 employees. The strengths of the University are wide multidisciplinary study and research interests, modern research and study environment and extensive cooperation with international educational and research institutes.


The Faculty of Science at the University of Oulu is announcing an open

Postdoctoral researcher position,

which will be located at the Research Unit of Mathematical Sciences (http://www.oulu.fi/mathematics/) which has an internationally strong position at the forefront of research in its focus areas. The Research Unit is a partner in one Finnish Centre of Excellence in Inverse Modelling and Imaging (https://www.helsinki.fi/en/researchgroups/centre-of-excellence-of-inverse-modelling-and-imaging).

This position is aimed at strengthening the participating research units as well as the HiDyn program funded by the Academy of Finland PROFI5. Data Insight for High-Dimensional Dynamics (HiDyn) is a program devoted to multidisciplinary data science and artificial intelligence. It will offer mathematical and methodological expertise to understand high-dimensional dynamic systems.


Description of the position

The research project “Multi-task learning for high-dimensional prediction” aims to combine expertise in bioinformatics methodology with statistics and machine learning. Multi-task learning is a versatile and very flexible framework for prediction of large multivariate input and output data. The research will concentrate on developing and applying new methodologies of data science and artificial intelligence to tackle research problems related to bio marker analysis and prediction. New approaches for data fusion will also be considered.

The new Postdoc researcher is expected to write and publish scientific articles in international peer-reviewed journals documenting the achievements of the work. Some participation in teaching is required.
