Biography

I (Bjørn Sand Jensen) was a Lecturer in the Information, Data and Analysis Section in the School of Computing Science, University of Glasgow, from May 2016 to October 2021. 

As of 1st November 2021, I am an Associate Professor at the Technical University of Denmark and an Honorary Research Fellow at the University of Glasgow.

 

Research interests

  • Probabilistic (/Bayesian) machine learning
  • Planning/sequential decision-making under uncertainty (using principles from reinforcement learning, including Bayesian optimisation)
  • Audio processing and modelling
  • Eliciting and modelling human decision-making
  • Bayesian non-parametrics (especially Gaussian processes)
  • Uncertainty quantification in scientific inquiry (e.g. biological image analysis and digital humanities)
