I am a physicist, specialising in acoustics. My main focuses are physical acoustics and computational physics, although I have touched on many topics throughout my research career. Currently, I am working as a post-doc at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. I am also a co-chair of the Acoustics group of the Norwegian Physical Society.
2018–: Postdoctoral researcher, NTNU (CIUS)
At the Centre for Innovative Ultrasound Solutions, I am working with non-destructive testing in oil wells. Specifically, I am working on drawing more information from acoustic log data and applying it in new ways. I also worked as a teaching assistant in a course on various (though mainly ultrasonic) medical imaging methods.
2013–2018: Research scientist, SINTEF Digital (Acoustics group)
In the acoustics group of the research institute SINTEF, I mostly worked on contract research for Norwegian companies. This work covered a wide range of topics, including simulations of waves and vibrations in solids and fluids, traffic auralisation, mapping methods for environmental noise, and applying deep learning to sound processing and analysis.
2009–2014: PhD student, NTNU
I did my PhD at the acoustics group at NTNU’s Dept. of Electronics and Telecommunications. My topic was sound propagation in lattice Boltzmann simulations. This work led to four peer-reviewed journal articles, two conference articles, and one monograph thesis. During this period, I taught a course on computational acoustics for Master’s and PhD students and an introductory course on acoustics for Master’s students. I was also a teaching assistant in multiple courses.
2004–2009: Master’s student in Applied Physics, NTNU
I studied at the five-year integrated Master’s (Sivilingeniør) program in Physics and Mathematics at NTNU. There, I chose the Applied Physics specialisation, and focused on courses in acoustics, computational physics, and signal processing.
Books and monographs
The lattice Boltzmann method: Principles and practice (2017)
I am a co-author of this Springer Graduate Texts in Physics book. I co-wrote it with Timm Krüger, Halim Kusumaatmaja, Alexandr Kuzmin, Orest Shardt, and Gonçalo Silva from 2013 to 2016. Our book gives an approachable yet thorough introduction to the lattice Boltzmann method over the course of its 13 chapters. At the end of 2017, it was highlighted by Springer as their fifth most downloaded physics book published that year.
The lattice Boltzmann method: Fundamentals and acoustics (2014)
My PhD thesis consists of two parts. The first part is a general introduction to the theory that underlies my PhD work. It covers things such as a quick introduction to fluid mechanics and acoustics (including some aeroacoustics and nonlinear acoustics), the kinetic theory of gases, and the basics of the lattice Boltzmann method. The second part describes my PhD research on sound propagation in lattice Boltzmann simulations in a more unified and detailed manner than my individual articles do by themselves. It covers acoustic linearisation analysis, acoustic sources, and a method to vary the equation of state.
While the Springer textbook generally provides a better introduction to the lattice Boltzmann method, the thesis goes deeper into detail on some topics. You can freely download it from ResearchGate.
