Biography

I (Bjørn Sand Jensen) am a Lecturer in the Information, Data and Analysis Section in the School of Computing Science, University of Glasgow, working in the interdisciplinary field of probabilistic machine learning, mathematical modeling, interaction and data analysis.

In 2006, I received my Master’s degree in electronic engineering from the Technical University of Denmark, specialising in probabilistic machine learning and signal processing. From 2006-2009 I joined the R&D department of Bang & Olufsen ICEpower working on perceptual audio signal processing while also representing the company in the DANES research project as steering group member.

In 2009, I returned to the Technical University of Denmark to pursue a PhD degree on a fully funded university stipend under the supervision Prof Jan Larsen and co-supervised by Prof Lars Kai Hansen. I was awarded the PhD degree in Marts 2013 for my work on preference elicitation and machine learning for integrating subjective and objective observations using Bayesian and non-parametric methods. I continued my research as a Postdoctoral researcher in the Danish strategic research project CoSound, working with several partners from industry, public service and universities (the Royal Library, Denmark's Radio, Bang & Olufsen, Copenhagen University Humanities and Information Science, Glasgow University, Aalborg University) on large-scale analysis and enrichment of multimedia and cultural heritage archives. I was appointed Lecturer in the School of Computing Science, University of Glasgow in May 2016.
