Overview


The over-arching goal of my research is to provide the aviation community the tools it urgently needs to analyze, design and certify the next-generation aircraft that are safer, greener and quieter. To that end, I focus on developing efficient adjoint-based optimization methods and multi-fidelity simulation methodologies to enable efficient aerodynamic and aeroacoustic designs.

Since 2015, I have been one of the principal developers of the open-source SU2 software package for multi-physics analysis and design, leading the development effort in the area of aeroacoustic prediction and design optimization. Active users of the SU2-CAA solver include NASA, Embraer S.A. and a number of research groups in academia.

Meanwhile, I serve as a consultant to the NASA Langley Research Center on the topic of adjoint-based aeroacoustic design optimization.

In addition to aeroacoustic prediction and optimization, other areas of my research interest include: hybrid RANS/LES methods for turbulent flows, machine learning, design under uncertainty, and bio-inspired aeronautical designs.
