RESEARCH INTERESTS: My primary research interest is in Big Data Exploration. My research seeks to empower a knowledge worker with the ability to pose high-level search and analysis queries that help her analyze, search and explore large data repositories in a manner beyond the current capabilities of data management systems. This involves research in core areas such as databases, AI and machine learning, data mining, human-machine computation, information retrieval, and algorithms. My work is cross-cutting, and impacts a wide variety of application domains including social computing, cyber security, health informatics, the Web, location-based mapping services, crowdsourcing, and others. 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, as well as details of our students and collaborators. Center for Artificial Intelligence and Big Data (CARIDA): I am the Co-Director of the Center for Artificial Intelligence and Big Data (CARIDA) in the College of Engineering of the University of Texas. This center focuses on cutting-edge research in large-scale data analysis of very large, diverse data sets that arise in a multitude of real-world applications. The mission of CARIDA is to enable pursuit of grand-challenge problems in artificial intelligence and big data by synergizing the strong expertise in various disciplines across COE, UTA as well as external collaborators, with the goal of establishing UTA as a leader in big data technologies and services. Please see center website for further details. HONORS/AWARDS: 1.
