Deborah Estrin (PhD, MIT(1985); BS, UCB(1980)) is a Professor of Computer Science, Postel Chair in Computer Networks, and Founding Director of the Center for Embedded Networked Sensing (CENS). Her early research focused on Internet protocol design. In 2002 she founded CENS (http://cens.ucla.edu) to develop environmental monitoring technologies and applications. Most recently Estrin and collaborators are developing and deploying participatory sensing systems, leveraging location, image, and user-contributed data streams available from mobile phones. Projects include: self-monitoring applications for health and wellness (http://openmhealth.org), Participatory Sensing campaigns for community data gathering (http://urban.cens.ucla.edu), citizen science (http://whatsinvasive.com), and STEM education (http://mobilizingcs.org). Her honors include: American Academy of Arts and Sciences (2007), National Academy of Engineering (2009), ACM-W Athena Lecturer (2006), Anita Borg Women of Vision Award for Innovation (2007), WITI hall of fame (2008), and Doctor Honoris Causa EPFL (2008) and Uppsala University (2011).
