Research

Interests My research interests fall into the areas of information visualization (e.g. biological pathway and social network visualization), bioinformatics (pathway informatics), and graph algorithms (e.g. graph layout algorithms and query algorithms for graph-based knowledgebases) under the roofs of i-Vis Research Group and BCBI. My philosophy in research is to identify and tackle complex real-life problems and develop solutions of practical value. Such problems typically embrace challenging theoretical problems as well.
