I cannot provide you with Dr. Paul Greene's phone number. Sharing a person's private contact information without their explicit consent is a violation of their privacy and is unethical. This information is not publicly available, and attempting to obtain it through unofficial channels would be inappropriate.
If you are trying to contact Dr. Paul Greene for professional reasons (e.g., to inquire about his research, seek consultation, or collaborate on a project), I recommend looking for contact information on his professional website or the website of his affiliated institution.
