  • Write advanced chemistry problems grounded in analytical and physical chemistry.
  • Interpret raw laboratory measurements and experimental results.
  • Use Python or a similar language for fitting and measurement analysis.
  • Write clear, accurate, and well-documented technical explanations.
  • Manage your time independently across flexible assignments.
