RESEARCH INTERESTS

I am interested in developing semantic technologies in information integration, extraction, and presentation.  One of the specific problems I worked on was to discover, capture, and represent semantics  for heterogeneous data. The key was to use conceptual models including ontologies and semantic mappings to capture data semantics. I developed solutions to discovering mappings from schemas to conceptual models, mappings between conceptual models, and mappings between schemas using conceptual models.  I developed the MAPONTO semantic mapping tool in the past. Currently, I am interested in biomedical and health informatics. In particular, I am working with colleagues from Drexel College of Nursing and College of Medicine on developing solutions to some interesting problems such as how to use information technology to deliver personalized healthy living programs to underserved populations, how to manage the quality of electronic health data, and how to analyze health and biomedicine related big data, etc. Here is a list of topics summarizing my research interests:
  1. Health and Biomedical Information Integration, Extraction, and Analysis
  2. Requirements Analysis and Engineering for Healthcare Information Systems
  3. Semantic and Ontology Mapping
  4. Knowledge Representation and Reasoning
