Biology AI Content Evaluator & AI Trainer

TextRLHF
As a Biology AI Content Evaluator & AI Trainer, I evaluated and refined AI-generated biological and medical content using reinforcement learning with human feedback (RLHF). I developed and reviewed annotated datasets for model training, ensuring the accuracy and clarity of model responses in biology and medicine. I designed annotation guidelines and provided expert feedback on scientific reasoning and clinical applicability. • Evaluated, ranked, and refined 10,000+ biological and medical annotations. • Designed structured prompts and responses for AI training in cardiovascular diseases, molecular biology pathways, and human physiology. • Corrected conceptual and diagnostic errors in AI model outputs, including ECG interpretation and arrhythmia classification. • Developed datasets for image-based annotation tasks like X-ray, ECG, and echocardiography interpretation.
