Can a while clause be followed by the present perfect?
Is it correct to say the following?
- While working on my project I have found an interesting research paper.
I mean whether while and the use of present perfect in the same sentence is correct.
There is rarely good reason to make past or present perfect out of simple sentences. In my work I find people regularly bending over backwards to shoe-horn having or have into their descriptions. I tell people to avoid it except for meals; what are we having or what will we have to eat etc.
Is it English, yes. Is it correct, maybe just. Is it understandable, yes. Is it the way one should speak or write, no, it is possible but sounds strained and unnatural to a native speaker. Directness by way of simplicity is always the goal.
