Ryan Wolfe is a former police officer hired as a forensic scientist after veteran CSI Tim Speedle is killed on the job. He has a strong background in science, having majored in chemistry at Boston University and currently pursuing a master's degree in genetics. In his younger years, Wolfe was tormented by a bully in school. Wolfe had been saving his allowance to buy a telescope, which the bully later broke when he knocked Wolfe's bicycle over.
