logician
Deduction theory specialist
A logician is someone who studies or is skilled in logic—the systematic principles of valid reasoning and inference.
The term applies both to philosophers who develop logical theory and to anyone who reasons with unusual rigor and precision: She approached the problem like a logician, breaking it into its component parts.
