Joe,
This appears to be the collective use:
so Industrial Editor
depending on the PR classification
Financial editor, etc.

But the category in industrial may be indicated on the same line in parentheses latter such as (Industrial, medical laser) for example
even there Industrial editor seems appropriate.

My question would be whether it's a particular industry or whether it's the editor who deals with industry as a category within the paper's coverage? If the former, industry editor, if the latter, then industrial editor, as was suggested by Chizuko.
