About Me

I am a professor of Computer Science Department and the director of the Information Analytics and Visualization Center at Purdue University Fort Wayne (PFW). I obtained a Ph.D. in Computer Science from the Illinois Institute of Technology in 1998 and B.S. in CS from Inha University in 1988. During the years 2006 -2009, I served as the ACS Graduate Program director of IPFW. Throughout this time, I created a thesis option for The Master of Science in Applied Computer Science degree.

My research interests include information visualization, data analytics,
virtual reality, medical imaging, and computer science education.

  • Data Visualization
  • Data Analytics
  • Virtual Reality
  • Medical Imaging
  • CS education

My current study focuses on developing visualization techniques for multiple forms of digitized contents, devising visual analytics tools for health informatics, and studying the depth perception issues on stereoscopic devices. I have published about 60 articles, executed funded projects awarded by the National Science Foundation, State of Indiana, Purdue Research Foundation, Indiana University, Parkview Health System, and regional businesses, etc.
As the Executive Associate Director, I established the Information Analytics and Visualization (IAV) Center which is a Center of Excellence at PFW. The IAV Center opened on February 23, 2011 with a $500,000 grant awarded from the Lilly Endowment Inc. through the Talent Initiative program.


I have developed and taught a range of CS courses from freshman to the graduate level. Some of selected courses are Computer Graphics (Undergraduate and Graduate level), Information Visualization, Virtual Environment, Object-oriented System Development, Senior Capstone Project, various programming course (Java, C++, C), etc.
