Princeton-trained engineering PhD who drives complex, ambiguous technical work from open questions to validated outcomes. My background blends experimental and computational research with data science, and I communicate results clearly for both technical and non-specialist audiences. In my doctoral research, I owned multi-year programs end-to-end by scoping problems, setting roadmaps, coordinating across collaborators, and delivering publishable findings on schedule. I built Python and Mathematica pipelines to convert and analyze large datasets, developed 2D and 3D multiphysics models to validate experiments and identify design parameters, and delivered nearly 10 conference presentations with original figures and multimedia. Outside the lab, I have combined technical credibility with communication and execution. As an independent contractor, I develop and evaluate scientific prompts and responses for AI training, and I previously taught undergraduate and graduate coursework with Princeton’s Excellence in Teaching Award. I also managed full P and L operations and led program planning for a student-run hospitality venture, strengthening my ability to manage people, compliance, and measurable outcomes.
