can phd use dr title
If your have a PHD this confers the title Dr. Which you should not put on your email or business cards (either as Dr or PHD and most definitely not both!). In academia the title is redundant, in industry the title makes you pompous.hough when it is used it should be Dr John Smith, not Dr John Smith PhD. So if you are working as an academic of course it can be on your business cards. I do not use my title outside academia, but I do have it on my bank card.
