My primary research interests are in database exploration. My research seeks to empower a knowledge worker with the ability to pose high-level analytical queries that help her analyze, search and explore a data repository in a manner beyond the current capabilities of database systems. This involves research in diverse areas such as decision support, data summarization, similarity search, and mining of heterogeneous databases. I am also interested in the exploration, storage/integration and mining of databases that arise from emerging data sources, such as streams, sensor data, satellite imagery, and biological data. Database Exploration Laboratory (DBXLAB): Research projects in database exploration and data mining are carried out at the Database Exploration Laboratory - including several projects carried over from my past affiliation, the DMX group at Microsoft Research. We also actively collaborate with numerous other research groups, both internal and external to UT-Arlington. Please see the lab website for further details of these projects. In addition to my research in databases and data mining, I have also worked in computational geometry and combinatorial algorithms. One of my areas of interest is geometric network design, which is concerned with the design and analysis of geometric networks, such as Euclidean TSPs, graph spanners, shortest paths, and spanning trees. For example, graph spanners have been a fertile area of research, with new and exciting applications, such as in the areas of wireless ad-hoc networks and internet routing. |
