Lyle Rogers is the Director of Public Relations and Media for Sarif Industries. He appears in Deus Ex: Human Revolution in the prologue, discussing security matters with David Sarif, shortly before the company's head of security, Adam Jensen, arrives and interrups the conversation. Lyle then departs, and is not seen again.
His office in the building is number 21 on the second floor. On a computer found in his office, there is an e-mail from Sarif regarding Picus' recent coverage of the augmentation debate. It is clear from this e-mail that Sarif is not pleased with how Rogers has been handling public relations related to this situation.
