Overview

Open-source software development is a central pillar of my research program. This project focuses on the design, implementation, and long-term maintenance of community-driven scientific software for numerical simulation, with an emphasis on correctness, scalability, and reproducibility.

My contributions emphasize software as a research product, not merely an implementation detail.

Core Software Projects

• GeoClaw – Adaptive storm surge and tsunami modeling
  https://github.com/clawpack/geoclaw

• PyClaw – Python-based framework for solving hyperbolic PDEs
  https://github.com/clawpack/pyclaw

• Clawpack – Open-source ecosystem for wave propagation problems
  https://www.clawpack.org

These tools are used internationally in research, education, and applied hazard modeling.

Design Principles

These software efforts support research areas including Numerical Methods for Hyperbolic PDEs, Coastal Flooding & Storm Surge Modeling, and Uncertainty Quantification & Risk.

• Close coupling between numerical methods and software architecture
• Performance portability across HPC platforms
• Transparent algorithms enabling reproducibility
• Extensibility for interdisciplinary applications
• Community engagement and mentorship

Impact

• Broad adoption in geophysical and applied mathematics communities
• Support for reproducible, open computational science
• Training of students and early-career researchers through real research software
• Long-term sustainability of research codes beyond individual projects or grants
