I am struggling with the use of both present perfect and past simple tenses in the same line, which I will add to my formal writing.

I just want to know if the following sentence is grammatically correct and meaningful:

"Dr. Gregory's works on AI have introduced me to several questions that I never considered before"

Please help... Thanks...

This is totally acceptable. For one, the simple past (aorist) considered is in a different clause, so it's a whole other little idea. You've got one completed action "have introduced" and one past action. You could put any tense here that appropriately describes the action. It could be future . . .

". . . that I will never answer."
