RESEARCH INTERESTS: My primary research interests are in Big Data 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 large data repositories in a manner beyond the current capabilities of database systems. This involves research in diverse areas such as databases, data analytics and mining, social computing, hidden web, information retrieval, and algorithms.
Database Exploration Laboratory (DBXLAB): Research projects in data exploration are carried out at the Database Exploration Laboratory at UT-Arlington. 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.
