During the fall 2011, I was teaching the masters level course "Mathematical Models, Analysis and Simulation". Information about the course can be found here. I will teach this course also during fall 2012. In the fall, I will also teach a course in Applied Linear Algebra, within the new Bachelor program in Simulaton Technology and Virtual Design. |

Master Thesis projectThe 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 InterestsNumerical 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.
I am currently supervising the following PhD students: Oana Marin Ludvig af Klinteberg Jennifer Gruenig and a postdoc Rikard Ojala. My former PhD students: Dag Lindbo , PhD, KTH 2011. Shilpa Khatri , PhD, NYU 2009. |

I am active within the Swedish e-Science Research Center (SeRC) through the core community in Numerical Analysis. In the fall 2012, we are initiating a new project in collaboration with the Molecular Simulation community. The project concerns fast methods for electrostatic calculation in molecular dynamic simulations. |
