Maths Halstensen

Professor Maths Halstensen is a distinguished faculty member in the Department of Electrical Engineering, Information Technology and Cybernetics at the University of South-Eastern Norway (USN), Faculty of Technology, Natural Sciences and Maritime Sciences, Campus Porsgrunn. With a career spanning over two decades since his 2002 PhD, he has established himself as a leading expert in chemometrics and process analytical technology, maintaining continuous research output through 2019 with significant contributions to industrial monitoring systems.

His academic journey includes:

• PhD in Acoustic Chemometrics from NTNU (2002)
• MSc in Process Automation from Telemark University College (1997)
• BSc in Industrial Electronics from Gjøvik University College (1995)

Professor Halstensen's research program centers on developing multivariate data analysis techniques for industrial process monitoring, with particular emphasis on:

• Acoustic chemometrics for multiphase flow characterization
• CO2 capture process optimization using spectroscopic methods
• Real-time monitoring of scale deposition in pipelines
• Multivariate regression modeling for energy and process prediction
• Raman and NIR spectroscopy applications in industrial settings

His work bridges theoretical chemometrics with practical industrial implementations, focusing on solutions for metallurgy, chemical processing, and carbon capture sectors.

Analysis of his 15 most recent publications reveals a dominant focus on carbon capture technologies (60% of recent work), particularly equilibrium measurements in ammonia-CO2 systems and real-time monitoring of absorption processes. His research demonstrates consistent application of multivariate modeling to solve industrial challenges, with strong emphasis on sensor development and practical implementation. Key methodological contributions include acoustic chemometric approaches for velocity measurement and novel calibration techniques for complex industrial mixtures.

As leader of the ACRG Laboratory, Professor Halstensen directs research in:

• Acoustic sensor development for industrial environments
• Spectroscopic monitoring system integration
• Multivariate data analysis for process optimization
• Real-time control system implementation

His teaching encompasses BSc, MSc, and PhD levels with focus on practical engineering skills. The research group benefits from institutional support through USN's strategic focus on 'Energy, climate and the environment,' with likely connections to Research Council of Norway funding and EU research programs. Professor Halstensen maintains active industry collaborations through his applied research on process monitoring solutions for energy-intensive industries.
