Apostolopoulos is CTO of Cisco’s Enterprise group, coming over from rival HP about six months ago. He also leads Cisco’s Enterprise Networking Labs. He has lots of experience at that from HP: Apostolopoulos was director of HP’s Mobile & Immersive Experience Lab and Distinguished Technologist in HP Labs. While in HP’s MIX Lab, Apostolopoulos sought to create networked media experiences that change how people communicate, collaborate, socialize and entertain. This included research on mobile devices and sensing, mobile client/cloud multimedia computing, video/audio signal processing, multimedia networking, vision & graphics, glasses-free 3D, next-generation plastic displays, wireless, and user experience design – many things Cisco is looking to lead in.
