Research Interests

• Uncertainty quantification (UQ) problems involving nonlinear hyperbolic PDEs.
• Reduced order models (ROMs) of parametrized hyperbolic PDEs.
• Discrete Radon transform (DRT) and its applications
• Probabilistic tsunami hazard assessment (PTHA)
• Inverse conductivity problem with power densities in dimension three.

Biography

Donsub Rim is a Chu Assistant Professor of Applied Mathematics. Before coming to Columbia, he received his Ph.D. in Applied Mathematics in 2017 from the University of Washington where he studied uncertainty quantification (UQ) problems arising in tsunami modeling and reduced order models (ROMs) for hyperbolic partial differential equations. His current research continues to focus on the development of ROMs and related numerical techniques that help tackle UQ problems such as the probabilistic tsunami hazard assessment (PTHA).
