Summary
👤
Senior🎓
Top SchoolJohn Jasa is a Senior Researcher and multidisciplinary design optimization engineer with a decade of experience building computational tools for hybrid energy and aerospace systems. Currently at NREL’s Wind Hybrid Systems group, he focuses on systems engineering of hybrid power plants that integrate wind, solar, storage, and novel end-uses like hydrogen and steel production. He brings strong MDO skills from a PhD in Aerospace Engineering and prior roles at NASA Glenn, where he applied optimization methods to propulsion and coupled-system problems. An active contributor to OpenMDAO, John has improved documentation and debugging capabilities for derivative analysis and developed educational notebooks to make advanced MDO tooling more accessible. Known for blending rigorous research with practical engineering, he often centers geometry representations and multifidelity data fusion to accelerate optimization workflows. Based in Lincoln, Nebraska, he combines lab-to-field perspective with open-source practice to move complex energy and aerospace concepts toward real-world deployment.
