As an AI Trainer and Subject Matter Expert in Physics and Scientific Reasoning, I contributed to improving large language models through rigorous evaluation and prompt engineering. My responsibilities included designing high-quality prompts, constructing reference solutions, and developing grading rubrics for advanced scientific topics. I assessed model responses for factual, mathematical, and logical accuracy and ensured alignment with scientific standards. • Contributed to training data for LLMs on physics and material science tasks. • Designed and reviewed prompts and model-generated content for complexity and accuracy. • Evaluated LLM outputs for academic and scientific integrity. • Worked remotely with teams at Outlier, Mercor, and Alignerr.
