About Me

I am a PhD Candidate in Informatics at UC Irvine. I am interested in natural language processing and human-computer interaction with a focus on health-related topics. More information can be found in my CV.


My research goals:

  • Develope tools to assist efficient use of health-related data
  • Discover pitfalls in current healthcare systems
  • Extract valuable information from biomedical literature
  • Investigate the general public's understanding and responses to health-related events
