The best research I've done didn't answer the question on the brief. It changed the question entirely. Teams came in asking whether users understood a feature and left reconsidering whether the feature was solving the right problem. To me, that's the actual job: not confirming what a team already believes, but changing what they think is possible.
Before UX, I was a Speech-Language Pathologist, which meant sitting with people who knew exactly what they wanted to say but couldn't find the words to match. That habit has carried over in my research practice: noticing the gap between what people intend and what actually comes out.
8+ years of hands-on research and research leadership at Instagram and Duolingo taught me that the research question is almost never the real question. I've led generative studies that shifted roadmap priorities, usability research that caught critical failures before they shipped, and longitudinal work that traced how people's relationships with a product evolve over time.
I'm available for senior and staff IC roles, contract or full-time, and open to the right research-leadership opportunity. I'm most interested in teams where the research can change what they think is possible.
what I do
Research Strategy
Most briefs arrive with the wrong question already baked in. I get involved before the brief exists, so the team is precise about what it actually needs to learn.
Qualitative Research
Interviews, ethnography, diary studies, usability testing. The craft is making it safe for people to say the true thing instead of the polite thing.
Mixed Methods
Stories land harder with numbers behind them. I partner with data scientists and build surveys that pressure-test what the interviews suggest.
Synthesis & Storytelling
Fieldwork is half the job. The other half is deciding what the patterns mean, what order to tell them in, and what format the decision-makers will actually read.
Communication & Language
I was a Speech-Language Pathologist before UX. I spent years diagnosing exactly where communication breaks down – turns out that's this job too.
Stakeholder Influence
Doing research and getting it used are different skills. I track who decides, what they need to hear, and when they're genuinely open to changing course.
