AI Evaluator | PhD Cognitive Science | ML, Scientific Review & Ethics

I am a PhD-trained researcher specializing in AI evaluation, machine learning, scientific reasoning, and ethics. I help clients assess AI outputs, review technical and scientific content, design evaluation criteria, and improve the clarity and reliability of complex material. My background spans artificial intelligence, cognitive science, neuroscience, philosophy, and reinforcement learning. This allows me to evaluate not only whether an AI response is fluent, but whether it is accurate, coherent, well-reasoned, and appropriate for the task. I can help with: * AI/LLM response evaluation * Scientific and technical review * Prompt and rubric evaluation * Research summaries and literature reviews * Academic and technical writing * AI ethics and philosophy-related content * Data analysis and interpretation I work carefully, communicate clearly, and focus on delivering precise, useful feedback. Looking forward to working together <3
