Tongji Data Management and Bioinformatics Laboratory

About DMB

The DMB (Data Management & Bioinformatics) group is under the Department of Computer Science & Technology , Tongji University. The group studies a broad array of topics including advanced data management and bioinformatics.

The DMB group has established collaboration relationships with professors and scholars from a number of universities and institutes, including National University of Singapore, City University of Hong Kong, Polytechnic University of Hong Kong, Hong Kong University, Drexel University, and IBM Watson Research Center etc.

Research topics

Data Management

Data management involves in P2P networks and other distributed environments (e.g. queries processing in P2P networks, distributed skyline computation), and data mining, including spatial clustering, text classification, outlier detection


In biology, Bioinformatics is an interdisciplinary field that develops and improves upon methods for storing, retrieving, organizing and analyzing biological data. A major activity in bioinformatics is to develop software tools to generate useful biological knowledge.

Spatial Database

A spatial database is a database that is optimized to store and query data that is related to objects in space, including points, lines and polygons. While typical databases can understand various numeric and character types of data, additional functionality needs to be added for databases to process spatial data types.

Image Processing

Functional neuroimaging has become an important tool to study brain organization over the past two decades. Functional magnetic resonance imaging (fMRI), in particular, has drawn considerable attention since it is noninvasive and has a high spatio-temporal resolution. There are two types of fMRI data, resting state and task state. In typical fMRI studies, the acquired data are analyzed to detect differential activation or obtain the functional connectivity, either over the whole brain or within particular regions of interest. Since many neurological disorders can change patterns of brain activity observed in functional imaging studies. These functional differences may be useful for classification of individuals into diagnostic categories. The work can be used to do disease diagnosis, etc.
