Pasadena, California

• Defined implementation and verification strategies for 4 part-time developers responsible for maintaining and extending the software packages written during my graduate studies.
• Developed custom source code build and pre-processing tools to implement unique project features.
• Planned algorithm and software infrastructure updates to achieve the goals of recently-funded projects.

Pasadena, California

• Analysis and modeling: Used statistical analysis, linear algebra, and signal processing techniques to succinctly and accurately describe unsteady (e.g. turbulent) flows in order to rigorously verify/validate new.
• Software development: Implemented research algorithms using Python, Fortran, C, and MPI (20 libraries, 400K lines of code). Correctness and state-of-the-art performance were extensively verified (tested on 25M CPU.
• Large datasets: Analyzed an aggregate of over 5 Petabytes of partially-structured data using custom-built parallel tools, Python, Paraview, and Matlab. Conducted numerical investigations on turbulent flows requiring.
• Applied mathematics: Constructed novel fast numerical solvers for elliptic difference equations that achieve state-of-the-art computation rates and parallel efficiencies. Published numerical experiments demonstrate.
• Computational fluid dynamics: Developed new robust, fast, parallel numerical methods for simulating fluid flows past complex geometries using novel structured/unstructured grid coupling, dynamic grid adaptation, fast.
• Project management: Individually responsible for the life-cycle (idea, design, implementation, and analysis) of 3 research projects in the field of numerical analysis during a 6 year period. Procured $1 million worth.
