"A Simulation Is Only As Good As Its Algorithms"
Xinfeng Gao's research is focused on the development of high-performance computing (HPC) computational fluid dynamics (CFD) algorithms for a wide range of applications in aerospace and mechanical engineering, involving shock waves, turbulence, combustion, plasma, and multifluids. Her research is categorized into three areas:
The development of numerical algorithms for complex partial differential equations (PDEs),
HPC and software engineering,
The development of enhanced CFD modeling & simulation (M & S) tools by data analytics.
Integrating these research capabilities together, she has been collaborating with national labs, universities, aerospace industry and software companies to transform research across scientific disciplines for solving complex problems of national and societal interest. Her research has been supported by the National Science Foundation, Air Force Office of Scientific Research, Department of Energy Laboratories, e.g., Lawrence Berkeley National Laboratory (LBNL), Lawrence Livermore National Laboratory (LLNL), etc, and Aerospace Industry, e.g., the Boeing Company, the Woodward Inc., etc.

Directorate for Technology, Innovation and Partnerships Translational Impacts
This MCA project aims to transfer computational fluid dynamics (CFD) and data assimilation (DA) technology from a research setting to commercial industry, partnering with Convergent Science who has experience with fast, predictive CFD for innovation in engineering. This partnership will allow Gao to make CFD+DA a design and analysis tool, accessible to non-experts. Industrial engineers will apply this reliable, accurate, and efficient technology in their product-design workflows for enhanced productivity.
