Deborah Estrin (Ph.D. MIT, 1985; BSEE UCB, 1980) is a Professor of Computer Science at UCLA, holds the Jon Postel Chair in Computer Networks, and is Founding Director of the NSF-funded Center for Embedded Networked Sensing (CENS). CENS mission is to explore and develop innovative, application-focused, distributed sensing systems, from ecosystems to human systems. Deborah’s earlier work focused on Internet scaling, including inter-domain and multicast routing. Since the late '90s her work has focused on multi-disciplinary, experimental-systems research and development as applied to a variety of environmental monitoring challenges. Most recently this work includes participatory-sensing systems, at the personal and community level, leveraging the location, acoustic, image, and attached-sensor data streams increasingly available from mobile phones.
