Here are a few of the projects on which I have worked. These include design studies, experimental evaluations, and usability studies.

Note-Taking Interfaces

My doctoral research involved the design, development, and evaluation of online note-taking interfaces to promote positive learning behaviors. The following are my two most recently completed projects, and include iterative design studies and experimental evaluation.

Highlighting is currently supported in a variety of ways online. I determined how users prefer highlighting to be supported.
Restricting Selection Size
This work explores how to encourage students to make shorter selections when copy-pasting notes.

Usability Studies

I have conducted usability evaluations and redesigns both for the Open Learning Initiative at Carnegie Mellon, and when I was working in Industry.

Usability Evaluation for Statics course
As HCI Consultant for the Carnegie Mellon Open Learning Initiative, I conducted many usability studies for a variety of online learning technologies. I collaborated on the early evaluation of the content and interactive elements for the OLI Statics course with Bill Jerome.
Digital Jones Redesign
Digital Jones Shopping Advisors Redesign
Digital Jones (bought by created online interactive shopping advisors. I co-led the first site redesign, using heuristic evaluation and think-aloud studies. I am currently putting together further information on this project.

Future Miscellaneous

I have done a variety of additional work using relevant techniques, and will put up descriptions as time permits. For now, permit me sentence-long descriptions of two of them. As a Knowledge Engineer at Digital Jones, I used field observations and structured interviews with experienced consumer electronics salesmen to create expert-system based shopping advisors. As part of a class project published at the Human Factors conference my colleagues and I studied social networks in a military command and control organization.

Mixed Methods
I favor decisions based on multiple lines of inquiry. For this reason much of my work combines methods, such as questionnaires, observation, and interviews. These methods can provide complementary data.
Central Techniques
Heuristic Evaluation
Semi-Structured Interviews
Experimental Evaluation
You rarely get it right on the first try. Getting user data early is the best way of avoiding ratholes. Part of my doctoral studies involved developing an iterative design process for rapidly gathering user data on multiple interface solutions.
