Teaching Experience

Instructor, Department of Computer Science, Virginia Tech
  • Software Engineering - Graduate-level course (Fall 2008)
  • Introduction to Problem Solving in Computer Science - Undergraduate-level course (Fall 2008, Spring 2009)
  • Usability Engineering - Graduate-level course (Spring 2008)
  • Human-Computer Interaction - Junior/senior-level undergraduate course (Summer 2004/2005, Spring 2009)
Graduate Teaching Assistant, Department of Computer Science, Virginia Tech
Assisting in teaching, grading assignments and tests, conducting in-class activities, and sometimes lecturing:
  • Usability engineering – Graduate course (Spring 2003/2004, Fall 2004/2006)
  • Human-computer interaction – Junior/senior course (Summer 2003, Fall 2003/2005, Spring 2006)

Selected Research Threads

Supporting group decision making in affinity diagramming activities using software tools: Currently part of a team researching the core phenomena that influence consensus building and collaborative work
  • Conducted four observational studies of participants creating affinity diagrams
  • Identified three candidate ideas for tools supporting group decision making: shared awareness, cognitive offloading, and understanding, organizing and searching
Continuous User Interfaces (CUIs) for multi-platform user interaction: Currently part of three-member research team addressing the problem of task-disconnect that users face when migrating a task from one platform to another
  • Defined task-disconnects (break in continuity that occurs when a user attempts to accomplish a task using more than one computing device) and introduced the concept of CUIs
  • Developed a software framework to bridge this task-disconnect, enabling users to seamlessly transition their tasks among different devices
Embodied data objects for tangible interfaces to information appliances: Researched alternative and novel interaction paradigms to mitigate the increasing complexity of computing devices and platforms
  • Applied the notion of using tangible everyday objects as embodied representations of active digital media
  • Prototyped two service-oriented information appliances (printer and presentation projector) which provide specific “computing” services as dictated by context of interaction
  • Designed a framework to support more types of services with little changes to existing setup
Visualization of usability data/metrics for usability process improvement: Started and led a research group that designed and developed Visability, a tool for visualizing usability problem data
  • Tool provided problem trends, what-if analysis capability, aggregate analysis, and ability to view recurring issues within usability engineering life cycle
  • Advised and mentored a graduate student who extended this project as his master’s thesis
Conference design for NSF’s AdvanceVT project: Was part of six-member research group to design a conference for women entering academe in the sciences and engineering
  • Conducted extensive literature review on learning theories, human cognition, gender bias, etc.
  • Conducted interviews and focus groups with women and faculty members in academe to determine problems and potential solutions for increasing female representation in sciences and engineering
  • Introduced the idea of a “Social Affordance” and created four design heuristics grounded in human information processing theory for use by future conference designers
