ELECTRICAL ENGINEERING 2012-2013 3 Network Coding, Wireless New Faculty Networks and Network Security Associate Professor Christina Fragouli The focus of Professor Fragouli’s research is on how cols for sensor networks. Professor Fragouli is among to make communication networks more efficient, reli- the pioneers in the area of network coding, with two able and secure. We increasingly rely on communication monographs and more than 80 journal and conference networks for services that are considered fundamental, publications in this area. such as education, news coverage, health and entertain- ment. Yet as the demand for network services increases, Wireless networks so do our requirements and expectations: we require and Professor Fragouli works on developing new physical expect availability, performance, security, and cost-effi- layer and packet layer cooperation schemes, that extract ciency.
