Biography

Sara Zahedi is a Professor at KTH Royal Institute of Technology in the Department of Mathematics. Her research bridges mathematical theory with practical applications, focusing on improving numerical algorithms to enhance the accuracy and efficiency of computer simulations. Her work centers around computational methods for solving partial differential equations (PDEs) in evolving domains, particularly in multiphase flow simulations and interfaces separating immiscible fluids. Her expertise includes Finite Element Methods (FEM), renowned for their efficiency in solving PDEs in complex geometries. Traditional FEM, however, typically require re-meshing to handle large deformations, necessitating conforming meshes to ensure accuracy and robustness. To address these challenges, she works on advanced Cut Finite Element Methods (CutFEM), which allow for evolving geometries to intersect operational meshes arbitrarily while maintaining accuracy. She earned her doctorate from KTH with a dissertation on numerical methods for fluid interface problems and subsequently held a postdoctoral position at Uppsala University. In 2016, she was awarded the European Mathematical Society Prize for her outstanding contributions to mathematics as a young researcher and received the Wallenberg Fellowship in 2019, which has been extended through 2024. She currently serves as an Associate Editor for the SIAM Journal on Numerical Analysis (SINUM) and participates in the SCI Faculty Board to enhance collaboration and transparency in faculty decision-making.
