Her current research interests are in extending
data management technology to support wireless sensor
networks, especially geosensor networks. Her research focuses
Dr. Nittel investigates the extension of data stream
engines(DSEs) for real-time
analytics of massive amounts of spatially distributed
sensor data streams.
These sensor data streams sample spatially and temporally continuous phenomena
such as environmental phenonmena or indoor ambient fields.
A second research area focuses on the real-time analytics of
manufacturing data such as machine vibrations of large robotics drills.
Her second research focus is on in-network
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.
Algorithms for in-network intelligence also include
applications of geosensor networks in intelligent transportation
networks, mobile ad-hoc ocean drifter sensor networks and the
LocalAlert approach for
decentralized coordination in emergency situations.
The third resarch area focuses on
understanding events monitored
by sensor networks through the integration of sensor network data, DBMS
and ontologies (in collaboration with Dr. Hahmann).
She is the co-founder of the conference series "Geosensor
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.
