Academic work

I develop  innovative stochastic models that try to carefully represent fundamental principles, basic dynamics, intricate patterns of dependence and mechanisms of the system to be understood or predicted.

In this way, models can answer specific questions, qualitative or quantitative in nature, and posses more power. Inference is usually based on computationally intensive stochastic algorithms. I prefer the Bayesian approach, but many of my projects are likelihood based. I am developing methods that inject a-priori knoweldge into machine learning.

I am director of the centre of excellence Integreat, the Norwegian centre for knowledge-driven machine learning, funded by the Research Council of Norway, the University of Oslo and the University of Tromsø. The centre operates from 2023 for ten year. Integreat contributes to make machine learning more sustainable, accurate, trustworthy and ethical.

In the last years I led the Oslo Center for Biostatistics and Epidemiology (OCBE) at the Faculty of Medicine and the centre for research-based innovation BigInsight, a consortium of industry, business, public institutions and academia, developing model based machine learning methodologies for big data.

My story

Since 2003, I am Professor in Statistics at the Oslo Center for Biostatistics and Epidemiology, University of Oslo. I have an adjunct position (20%) at the  Norwegian Computing Centre. Previously I have been working at the Oslo University Hospital, the Norwegian Computing Centre, the University of Roma III, the University of Venice and for IAC at the Italian Research Council in Rome. I am a mathematician by training. I have supervised more than 40 PhD students and have guided many postdocs. My research has been generously funded by many sources, including the Research Council of Norway, the European Union, NordForsk for the Nordic Council of Ministers, the South-Eastern Norway Regional Health Authority. I am currently employed at the Institute of Basic Medical Sciences (60%) and at the Department of Mathematics (40%) of UiO.
