Dr. Gil Grissom

Gil Grissom is the head of the Las Vegas Criminalistics Bureau. An investigator of the old school, with seventeen years on the job, Grissom eschews computer simulations and readouts for hands-on technique and legwork. CSI is his life. He supervises a team of very diverse professionals, and often goes to the wall to protect them from department interference - and sometimes, from the consequences of their own risky decisions, on and off the job.
