Do you need to get a better handle on your audience or a better understanding of the experience that your website or app is providing? Along with user interfaces, I can also design, implement, and report a range of user research and usability studies, including:
usability testing and task analysis
surveys, interviews and focus groups
personas, user scenarios and journeys
use cases, card sorting, and information architecture
I apply variations of user-centered practices is almost all that I do, from UX design and data visualization to creating course content and workshops that appeal to different learning styles.
