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.
