About

Nour Al Hassanieh

Assistant Professor of Mathematics

Nour El Hassanieh joined LAU as a full-time assistant professor of mathematics in 2026. Her research lies in the fields of numerical analysis, complex analysis, PDEs, and scientific computing.

During her PhD studies at Rensselaer Polytechnic Institute, she worked on finite difference methods for PDEs on complex geometries. She introduced novel boundary closures to support high-order-accurate finite-difference schemes with overset grids.

During her postdoctoral studies at New York University and the Flatiron Institute, she worked on developing fast and accurate algorithms for solving wave-equation problems using time-domain boundary integral methods. Specifically, she focused on 2D and 3D wave-equation scattering problems arising in applications such as acoustics, electromagnetics, and geophysics.

Research Interests

Dr. Al Hassanieh works on numerical methods for the wave equation and wave scattering applications.
