Applied Stochastic modelling with applications in Industry
Data science and modelling methods for retail, transportation and finance, where uncertainty, dynamics and operational decisions need to be handled together.
BI Norwegian Business School · Simula Research Laboratory
Professor of Data Science at BI and Adjunct Chief Research Scientist at Simula, working on mathematical and data science methods for complex time series in retail, transportation and finance.
About
I am an applied mathematician by training. My research is focused on mathematical and data science methods for complex time series data, with applications in retail, transportation and finance.
What keeps me curious is how mathematical structure can make complex data a little more useful.
Research
Current work is mainly concerned with complex time series in retail, transportation and finance, alongside stochastic modelling and reliable decision support.
Data science and modelling methods for retail, transportation and finance, where uncertainty, dynamics and operational decisions need to be handled together.
Feature representations for paths, images and time series, with an emphasis on memory, structure and interpretable learning.
Pathwise methods, stochastic differential equations, regularization by noise and Volterra-type systems.
Practical data-driven tools for decisions under uncertainty, developed with AMOR, SURE-AI and collaborators.
The tensordev repository by Paul Hager, Luca Pelizzari and collaborators provides efficient computation of Volterra signatures and related objects from recent preprints.
AI Notes
A dedicated place for notes, talks and public-facing reflections on AI, mathematical risk and reliable data-driven decisions.
Together with Andreas Ravndal Kostøl, I have written some thoughts on developing a strategic Norwegian-European AI investment fund constructed from the Norwegian Pension Fund and built around the same model, with the objective of strengthening European AI infrastructure and industry.
