In the Tv series NCIS is Abby a computer scientist?

After watching the NCIS complelte seasons 1-9 DVD, I found that Abby is good at computer. Could you tell me something about Abby? if she is not please tell me her job and the qualifications you need. 

A5: Actually, Abby is a forensic scientist and computer is her interest. To study this, you should have a degree of forensic science first. Also you need physics, geology, psychology, social science, etc.
