Joar Bagge

I obtained my PhD from KTH in 2023, under the supervision of professor Anna-Karin Tornberg, working on accurate numerical methods for fluid mechanics simulations. My main focus is on boundary integral methods, special quadrature methods and fast Ewald summation methods for simulating Stokes flow.

Since September 2023 I am a postdoctoral fellow at the Oden Institute, The University of Texas at Austin. My new profile page
