It's wrong to lie to get a job.
Nima is a physicist making his resume to get a tenure-track college physics professor position, something Nima didn't explicitly study.
Nima wants to impress the person who reads the resume.
Nima lists the degrees that he's earned and his work experience in the field of physics.
Nima says that he has a Ph.D. in a field that he actually doesn't have.
The department hires Nima for a research position in the physics department instead of a professor.
Nima is hired based on the fictional Ph.D. and realizes that he's completely incompetent for the job.
