            <h2>Data Centric Computing Lab, Konkuk University </h2>
<p><br> Welcome to the Data-Centric Computing Lab at Konkuk University!  <br> </p>
<p>Data Centric Computing Lab (DCCL) at Konkuk University specializes in the
design and implementation of high-performance storage systems and database
engines for next-generation data-intensive computing. Our research focuses on
the deep synergy between evolving hardware technologies—such as CXL,
disaggregated memory, and heterogeneous storage—and the core architectures of
data management systems. We specialize in architecting high-performance data
infrastructure at the systems level, optimizing the internal mechanisms of
Vector Databases, Time-series Databases, and Key-Value Stores. By fundamentally
rethinking the interaction between the storage stack and modern hardware, DCCL
builds the robust foundations necessary for autonomous and intelligent data
platforms.</p>
<p><br></p>
<h4>News: Undergraduate Research Internship Opportunity</h4>
<p>DCCL is currently seeking highly motivated undergraduate research interns to join our journey in pushing the boundaries of data-centric systems. This opportunity is exclusively open to Konkuk University students, and we highly encourage applications from those who have completed at least one of the following courses: System Programming, Operating Systems, or Database. If you are interested in gaining hands-on research experience, please send your CV and a brief introduction to <b>wookhee [at] konkuk [dot] ac [dot] kr.</b></p>
<h4>학부 연구생 모집 안내</h4>
