Senior R&D Engineer - Adjoint Solver at Ansys
Old Toronto, Ontario, Canada
Summary
👤
Senior🎓
Top SchoolDoug Shi-dong is a Senior R&D Engineer specializing in adjoint solvers and aerodynamic shape optimization, combining 11 years of software and research experience with a PhD in aerospace engineering from McGill. He builds numerical methods that solve large-scale PDEs with high-order finite element techniques and gradient-based optimization, and has applied that expertise at Ansys after stints as an SDE at Amazon and a 3D C++ developer at Align. Doug is an active contributor to the deal.II finite element library, focusing on bug fixes, QA, and templating derivative functions—evidence of his attention to correctness in complex scientific code. Comfortable bridging industrial product engineering and academic research, he enjoys applying aerodynamic optimization techniques to new domains that demand rigorous numerical solutions. Based in Old Toronto, he brings both production-grade software practices and deep mathematical instincts to tough computational problems.
