The Laboratory for Interdisciplinary Data Exploration and Analytics (IDEA Lab) addresses the growing demand of data science in multi- and interdisciplinary research. Building on our previous experience of deploying data science in the Semantic Web to support cross-disciplinary collaboration and scientific discovery, we aim at exploring the cutting-edge methodologies and technologies for participatory knowledge engineering, qualitative and quantitative modeling of complex systems, data interoperability and provenance, data curation and stewardship, visualized analysis of Big and Small Data, and the integrated application of them to tackle real world issues.

Apply to the Computer Science Graduate Program - We are looking for new PhD students with a background and interest in topics related to data science and geoinformatics - Contact Us to Discuss the Opportunities.

Research Areas

  • Design and implementation of models and knowledge graphs for complex systems in science
  • Data interoperability and provenance enablement with participatory approaches and semantic technologies
  • Exploratory analytics and visualization of spatio-temporal patterns in Big and Small Data
