Here's the context in question, please read on:
"The final proof is in the listening and John knows this. This knowledge makes him a designer in constant dynamic relationship with what he makes, rather than an applicator of proven scientific knowledge."
Can I use "Applicator of knowledge" to describe a person? How does it sound to native speakers? If it does not sound right, how else may I write the same sentence?
Thanks a lot, Maryam
