Forskning
Larsson's main research interest is numerical methods for partial differential equations, with a specific focus on methods based on radial basis function approximation. Some of the application areas that Larsson is working in are biomechanics and finance, but she also has publications on wave propagation, atmospherical flow and quantum dynamics. A secondary area of interest is parallel algorithms and parallel programming models, where task parallel programming is the main direction.
