Dr. Lindner has research interests in databases, medical and distributed information systems, wireless sensor networks and mobile computing, information system security, algorithms, and e-business systems. Recent and current research projects and initiatives include:

The Borealis Project:
Borealis is a second-generation distributed stream processing engine that is being developed at Brandeis University, Brown University, and MIT. Borealis inherits core stream processing functionality from Aurora and distribution functionality from Medusa. Borealis modifies and extends both systems in non-trivial and critical ways to provide advanced capabilities that are commonly required by newly-emerging stream processing applications.

Integrating Data Stream Management Systems and Sensor Networks:
We are currently developing an integrated query processing environment where users can seamlessly query both a data stream management system and a sensor network with one query expression. Some of the interesting research challenges that arise within the context of such environment are: the operator placement, the operator implementation, the storage placement, materializing views, and fault tolerance and reliability.

Data Management in Disconnected Sensor Networks:
There are many types of sensor-network deployments in which disconnections will be frequent and expected: in networks where the nodes are mobile, for example, nodes will become occasionally disconnected from each other. Similarly, in remote sensing environments, intermittent connections may be the only practical way to get data out of a network, e.g., when a satellite passes overhead or when a mobile node occasionally visits the remote site. To support operation in such environments, we investigate extending the networking capabilities of current sensor network query processors with explicit support for disconnection.
