Research Skills


  • qualitative research techniques, e.g. diary studies, interviews, focus groups, content analysis and usability testing

  • quantitative research techniques, e.g. surveys, scale development, log analysis, behavioral data analysis, data modeling

  • statistical analysis, e.g. mixed-effects multilevel models, ANOVA, t-tests, correlation, regression, and power analysis


  • Remote testing and video software & programs (UserTesting, Morae, Camtasia)

  • Wireframing technologies (Balsamiq, Gliffy)

  • Survey tools (Qualtrics, SurveyMonkey)

  • Statistical software (SPSS, R)

Research Projects
