Omar al-khayat joined the Simula team in September 2005 after finishing his M.Sc. in cosmological physics in June the same year. After working as a Scientific Programmer for six months, he started his PhD in April 2006 working with the development of numerical models in geoscientific applications. In 2010, Omar began his postdoctoral fellowship at Simula.

Turbidity flow modelling
Omar is developing a new computational framework for simulating transport of particles in fluid flows. One special feature of this framework is that it combines the best of existing frameworks: the particles can be viewed partly as individual particles, which eases the physical modeling, and as continuous clusters, which ensures high computational efficiency. Using the framework, we have been able to compute flows with high density of particles and get results in surprisingly good agreement with physical experiments.
