User Privacy and Social Networking Sites; Privacy Tradeoffs and Video Surveillance
Studied aspects of user privacy issues on social networking sites. Utilizing the survey methodology delivered via a third-party application. Expected outcome of study includes understanding motivations for user privacy tradeoffs on social networking sites e.g. privacy preferences with regard to third-party applications. Also helped to design and deploy a user study regarding privacy tradeoffs and video surveillance cameras in public spaces. Data collected included a questionnaire on user privacy attitudes, preferences and perceptions of video surveillance as well as structured interviews regarding privacy and security tradeoffs.

Data Visualization Design for Web Reputation/Claim Check System (ALPACA)
Currently designing a simplified data visualization for the user-interface (UI) of the ALPACA (A Lightweight Platform for Analyzing Claim Acceptability) reputation/claim check system. The purpose of the visualization is to inform users of the credibility or trust value of a reputation or claim being made, particularly in an online context. The primary thrust of the UI design is to use interaction-driven graph visualization techniques to represent claim/reputation credibility graphs generated by the ALPACA system. Users will interact with the interface to better understand the degree to which they have a basis for trusting reputations or claims.

“Computing for Social Good” Class Project – Mobile Kiosk Project for the Truth & Reconciliation Process (TRC) in the country of Liberia
Liberia is in a process of rebuilding the country from infrastructure to political institutions. Part of this rebuilding involves following what is called a Truth & Reconciliation process. In conjunction with the Liberian government, a team from Georgia Tech is working to provide technology tools for facilitating this process. One of the tools to be provided is a mobile kiosk where video testimony will be gathered and shared as part of the TRC efforts. My primary role in this project was to help design the shelter for the mobile kiosk as well as designing the form factor of the computer-based video monitor set-up that will be used both to record testimony for the TRC and also display publicly available testimony of other Liberians.

System Visualization to Inform End-User Security Decision-making
Co-winner of the “Tiger Team Usable Security Research Design Competition” (2005 & 2006). Submitted a research proposal with a student-partner for a novel way to help personal computer users make better security decisions and was awarded a total of four semesters of funding for the project. Independently developed visualization presenting security-related system state data in terms of spatial, physical metaphors, and concepts familiar to users. Designed, built and evaluated a functioning prototype tool employing this design. User study and evaluation results show that our visualization tool was statistically significant in helping users make better security decisions. Future work includes extending the visualization to end-user tasks related to firewall configuration in general and also as it relates to the home networking environment.

Adapting Personas for Security Visualization for Professional Information Analysts
Adapted and developed personas for project FirstLook; these personas were used to define the user requirements for a system to help professional intelligence analysts with the task of assessing information and monitoring meaningful changes in an information space. Explored and generated initial the design to graphically represent the auto-generated textual summaries of hundreds of thousands of text-based documents or news feeds. The designs were created so that the UI was interaction-driven and based on a combination of both geographic and narrative metaphors.

Network Health Visualization
Designed graphical interface for monitoring the health state for networks composed of “Secure Linux Appliances for PCS” devices. (These networks are used to help secure process control systems that monitor critical infrastructure such as nuclear power plants.) The interface design incorporated a tile-layout to represent data in different time scales and relied on zooming interface techniques to present network node details. Contributed to the initial implementation of the visualization in Java and OpenGL.

IDS Evaluation
Evaluated multiple intrusion detection systems for a proprietary network. Performed market survey of available systems, analyzed and tabulated the results in terms of features, functions, anticipated strengths and weaknesses. Defined the performance metrics for the evaluation. Created the test bed, conducted the evaluation tests and submitted report summarizing the evaluation findings.
