Dr. Silvia Nittel’s is an Associate Professor in the School of Computing and Information Science and a faculty member with the National Center of Geographic Information & Analysis at the University of Maine. She received her Ph.D. in 1994 from the University of Zurich in  database management systems, and joined the UCLA Computer Science Department as postdoctoral researcher in 1995. At UCLA, she worked on high-performance integration platforms for scientific data mining application for climate change. From 1998 to 2001, she was the Co-Director  of the UCLA Data Mining Lab. In Fall 2001, she started as a faculty member at the University of Maine.

Her current research interests are in extending data management technology to support wireless sensor networks for environmental applications, especially geosensor networks.In detail, she  investigates the extension of data stream engines (DSEs) for the support of processing, querying and integrating massive amounts of real-time mobile sensor data streams  representing continuous environmental phenomena in near real-time. In the past, her research focus was on in-network data aggregation algorithms for quantitative and qualitative spatial queries in geosensor networks to identify and track the boundary of events over space and time in a decentralized way, geosensor networks in intelligent transportation networks and mobile ad-hoc ocean drifter sensor networks.

She is the co-founder of the conference series "Geosensor Networks",  author of two books on Geosensor Networks and author of the topic "geosensor networks' in 4 encyclopedias .She is a recipient of a National Science Foundation Early CAREER award, and her research  has been funded with grants from NSF, NGA,  NASA and Maine National Guard. 

See  "A Survey of Geosensor Networks: Advances in Dynamic Environmental Monitoring" as an geosensor networks overview article,.
