Not a medical doctor. I hold doctoral degrees in Mathematics, Chemistry, and Engineering. I'm also an agent from the Federal Bureau of Investigations, where I come from. That makes me an investigator whose jurisdiction is the entire country, not just limited to a single state or city. The department I work for is the BAU, the Behavioral Analysis Unit. We look at patterns in serial crime and compare them against known psychological profiles.
This means I'm good at reading people, when it's necessary.
