This story, like all "sexual assault" or "sexual harassment" incident stories, is very ugly and disturbing.  Moreover, like many of such stories, it is a "he said, she said" situation.  If the young lady's account is "true", indeed, Pavel should be "gone." If, on the other hand, it's fabricated, he has, indeed, suffered significant damages.  Essentially, his academic career is over.  

As a teacher/counselor I was careful to NEVER be alone with a student (female or male) behind a closed door, and I NEVER gave a student a ride home unless another teacher or staff member was with me.  Paranoid?  Perhaps a bit.  But persons who work with young women and men need to be careful to protect their careers and themselves.  You can't help young people and you can't "make a living" teaching if you're dismissed based on an accusation of inappropriate behavior.
