Professor in Dept. of Math and CS

Working in Clemson University's newly minted Human Centered Computing division working on understanding relationship maintenance practices in online social spaces.

Created a Flash based temporal visualization tool called ClockWerk that allows the navigation of socially coded dialogue data from the in-game social interactions between EverQuest® II players.Developed a Flash and Perl based social visualization tool called ConnectDots that enables users to visualize interaction data collected from multiple media sources in order to aid them in better understanding their current decision making practices for managing and navigating their social networks.Implemented a MySQL database system back end to information visualization tool used to analyze news article corpuses to perform sensemaking and information analyst tasks using the collected data.Developed a Perl, Java, and JavaScript based toolbar called MetaLab that works in conjunction with the NetLogo modeling environment that archives relevant information for users running simulations in the modeling environment, and modified an online Wiki driven environment that allows for retrieval of the archived information and the presentation of other related information authored by users. Implemented a Perl based preference prediction system that applies document clustering techniques to RSS Feed document text for the retrieval of overall document context areas. Developed a web log community subscription application which cataloged user interactions within web log environments and managed this information through a database system. Designed a Perl based application that fields specific RSS Feed information delivered from a Movable Type based publishing system.

• Implemented an information visualization tool called the Term Concept Explorer that enabled users to view time serial representations of journal articles and their terms, to aid users in performing sensemaking tasks.• Conducted a user study to evaluate the performance of users asked to perform sensemaking tasks using the paper form of an article corpus and the Term Concept Explorer tool.

• Implemented a Perl and JavaScript based web toolbar that enables users to create pages that would include metadata relevant to browsed web pages or intranet pages encountered for the purposes of creating more informative process execution as performed from formal process documents.• Implemented supporting java functionality for an ongoing project to build a social navigation tool being developed by the Human Systems Research Group

Conducted background research on biochemistry modeling tools Gepasi and Virtual Cell for potential visual modeling of dynamic cellular interaction Investigated the special purpose markup languages, SBML and CellML Explored possible connective purposes of markup languages to enable automated data mining of biology databases for use in the creation of visual representations using the modeling tools explored
