Position

- Professor of Mathematics
- Professor of Computer Science (by courtesy)
- Member, Translation AI Center (TrAC)
- Data Science/AI Coordinator, Department of Mathematics

I am a Professor at the Department of Mathematics, Iowa State University. I work in a number of areas in Computational and Applied Mathematics, with research interests in the interplay of mathematical modeling of application problems by partial differential equations (PDEs), applied analysis, numerical methods, and scientific computing. My current work focuses on mathematical foundations for deep learning and data-driven methods for PDE-based problems.
