About

MSc in marine hydrodynamics from NTNU (2008). Have been working five years in the industry with hydrodynamic issues related to seakeeping and stationkeeping.

I graduated from NTNU, Dept. of Marine Technology in June 2008 with a MSc degree in marine hydrodynamics. My thesis was on the application of CFD to submarine pipelines, and was supervised by Prof. Bjørnar Pettersen.

The next five years I was working for DNV and Moss Maritime with hydrodynamic issues related to seakeeping and stationkeeping of mainly offshore structures. My experience from this period includes both numerical and experimental work.

In August 2013 I started as a PhD student at AMOS. My PhD work deals with hydrodynamic aspects related to AMOS project 7 which is entitled "Autonomous marine operations in extreme seas, violent water-structure interactions, deep waters and Arctic". The title of the thesis is "Nonlinear Wave Loads on Marine Structures in Extreme Sea States".

My PhD supervisor is Prof. Marilena Greco, while my co-supervisor is Prof. Odd M. Faltinsen.

Research

I do research in marine hydrodynamics with particular interest in

  • numerical methods for potential flow theory
  • nonlinear wave mechanics
  • nonlinear wave-body itneraction effects.

 

I do also have a keen interest in experimental hydrodynamics, signal processing and statistics of extreme values that I try to incorporate in my work.

During recent years, I have been continously involved in expanding the use of the harmonic polynomial cell (HPC) method proposed as an accurate and efficient numerical method to solve the Laplace equation for potential flows in marine hydrodynamics. My main contribution has been to explore the combination of the HPC method with immersed boundary strategies to deal with complex boundaries for nonlinear wave and wave-body interaction problems both in 2D and 3D.

Having significant experience from working in different companies in the industry, I strive to relate the academic research to practical applications when possible. At the same time I value fundamental research driven by curiosity.
