Labeling Experience

Physics & Math Content Specialist (AI Focus)

Text

As a Physics & Math Content Specialist with an AI focus, I developed structured physics problems specifically for AI training and evaluation. I evaluated AI-generated text solutions for logical consistency, accuracy, and correctness of reasoning. I refined step-by-step solutions to improve AI model performance. • Created structured math/physics problems for AI models • Evaluated and rated AI-generated responses • Validated numerical results using Python tools • Enhanced AI problem-solving through iterative feedback
