During the fall 2011, I am teaching the masters level course "Mathematical Models, Analysis and Simulation". Information about the course can be found here.

Openings for PhD students

In Februari, open positions for PhD students will be posted. The ad will be found on the KTH webpage, and I will post information here as well.

Master Thesis project

The dynamics of flexible fibers are very intriguing. As they are compressed, for example in a shear flow, they store elastic energy, that they later can release to the fluid, leading to a strong non-Newtonian behavior of a fluid-fiber suspension. I have developed an algorithm to simulate such fibers, based on a boundary integral method. In this project, we want to consider the case where the resting state of the fiber is not straight, but rather some other shape, like helical (think DNA!). GET IN TOUCH! to discuss this project, or other possibilities!

Research Interests

Numerical algorithms for solving PDEs in dynamic geometries, with the main application to multiphase flows. Interface tracking methods, including surface representation for dynamic interfaces, the development of algorithms for PDEs on these interfaces and the analysis and improvement of associated regularization techniques. Boundary integral methods, including slender body theory, quadrature methods and fast summation methods needed to accelerate the simulations.
