Biography
I joined the Computer Science and Engineering department in the Fall of 2022. My research interests include Data Management Systems, Big Data, Semantic Web, Knowledge Graphs, and Information Integration. Please email me if you are interested in collaborating with me on research or pursuing a Ph.D. in databases (especially if you are working in the industry and would like to pursue your Ph.D. as a part-time student).
