theoretician
One who hypothesizes
A theoretician is someone who develops or works with theories rather than their practical applications.
The term often distinguishes those who work abstractly from practitioners: She's a theoretician, not a bench scientist.
Theoreticians appear across fields—physics, economics, music—wherever foundational principles need articulation.
The word is interchangeable with theorist, though theoretician may carry slightly more formal or technical weight.
