Postdoc position in Statistics at the Oslo Centre for Biostatistics and Epidemiology (OCBE)

About the position and research group

A three-year postdoc/researcher position in statistics is available at the Oslo Centre for Biostatistics and Epidemiology (OCBE), Department of Biostatistics, Institute of Basic Medical Sciences (IMB), University of Oslo (UiO), Norway. The candidate shall take part in the research group on “Statistical models for high-dimensional and functional data”, led by Professor Valeria Vitelli. Successful candidates will work on Bayesian models for unsupervised learning when multiple data sources are available, mostly tailored to the case of dynamic sequential inference and probabilistic recommender systems. 

The position is connected to the project “Bayesian Rank-based unsupervised Integration of multi-source Data in cancer Genomics and the digital Economy (BRIDGE)”, funded in 2025 by the Research Council of Norway (RCN) under the open scheme “Researcher Project for Scientific Renewal”, and it is fully funded for 3 years. The project is conducted in close collaboration with the SFF Integreat, The Norwegian Centre for Knowledge-driven Machine Learning (ML), a centre of excellence funded by RCN and in operation until 2033. 

The research group on statistical models for high-dimensional and functional data is part of the larger and active research environment on “High-dimensional statistics” at OCBE. OCBE has expanded considerably during the last decade, becoming one of Europe's most active internationally recognized biostatistics groups with currently over 70 researchers.

Main tasks for the position

The candidate will pursue research on Bayesian models for unsupervised learning when multiple data sources are available, mostly tailored to the case of dynamic sequential inference and probabilistic recommender systems. Emphasis will be placed on rank-based models and their successful use in probabilistic recommender systems, but many other research topics may also be relevant for the project, such as scalability, post-Bayesian methods, and in general computational and methodological challenges in integrative unsupervised learning. Method development will be motivated by the research questions of the funded project, but the candidate will be also free and encouraged to pursue her own research agenda.

Being part of a larger funded research project (3 positions in total), the candidate will work closely with other project members at OCBE to pursue common research objectives and will participate in regular project meetings. Therefore, ability to work in a multi-disciplinary team is essential. The candidate for this position will specifically contribute to the project by successfully developing methods to integrate large and complex preference datasets with information at individual level, with specific attention to open and reproducible research, e.g., in the development of codes and algorithms. We will focus on devising computational solutions that can immediately be of use in other applications contexts as well. The candidate’s work will entail the development and implementation of statistical methods, as well as data analyses, preparation of manuscripts and communication of research findings. The funded research project team, as well as the broader research group on high-dimensional statistics at OCBE, provide a friendly and stimulating international research environment.
