About me
I work as a scientist at SINTEF Energy Research in Trondheim, Norway. My research interests mainly lie in the intersection between fluid mechanics, molecular dynamics and thermodynamics, with a particular focus on interfacial phenomena.
For my PhD, I developed multiscale numerical methods for understanding small water drops inside oil, and how they behave when subjected to an electric field. Using molecular dynamics, I worked on computing interfacial properties caused by real crude oil components called asphaltenes, and subsequently we used these properties in CFD simulations to explain the crumpling of droplets which are deflated. You can read all about it in my thesis (PDF), or look at a slide show based on my thesis defence (big file, takes time to load).

My office is in room A306 of "Varmeteknisk laboratorium".
Besides the science:
I live in Trondheim, Norway with my wife Elisa and my daughters Aurora and
Runa. In the winter I go skiing alot, and in summer I skateboard and
snorkle when I can find the time. Sometimes
I take my Fortran and go
code golfing.

Reproducible science:
As students we are taught that science should be reproducible, but the
rapid evolution of computational science has left this ideal as often
unfulfilled.
The current
"Reproducible
Research"
movement
aims to rectify this. I strive to live up to this ideal through the data, code and documents posted at
my Figshare
site and at my Bitbucket
site.
