Who am I supposed to be? I want to join the FBI but I also want to be a mad scientist.?

I meant a scientist on the cutting edge of science or a hard punching and shooting FBI agent who pursues strange phenomenon with the department of Homeland Security...what should I do.... I have to write this mega statement about who I am and what I want to be just to be considered for re-admittance into my university so I have to be sincere. It's going to be reviewed by a big committee and this is to get back in after failing while on academic probation. Another words, I have to convince them to let me back in because my suspension is indefinite.
