Physicist or chemist (PhD): research-level problems and literature review

Pay: $125-$200/hr The work Write graduate-level problems with full derivations in your field; grade model attempts and locate errors in reasoning, units and approximations; review model-generated summaries of research papers against the papers themselves; evaluate proposed experimental designs. Who it suits PhD in physics, chemistry, materials science or chemical engineering, with published research. Theoretical and experimental backgrounds both needed. How it works We verify your credentials, licence or degree and your identity before any paid work. Every piece of work traces to a named, verified expert. A paid calibration task on the project's own guidelines comes first. You are paid at the rate on this page for every hour of work that passes review. Rates rise with the difficulty of the project and your track record. HUMXN is a new expert network (launched 2026). Payouts go through Stripe after identity and tax verification.
