My portfolio showcases an impressive track record of shipping 65+ successful products, informed by over 500 studies, and of shaping 4+ research teams from 0 to 1.

Habit formation & engagement: How do users build routines? What breaks them? I've studied daily behavior longitudinally — from skincare patients to daily traders — and translated those patterns into retention-driving product changes.

Growth & subscriptions: Freemium conversion, willingness-to-pay, churn diagnosis, referral mechanics. I've run the full research stack on subscription products at scale, including a regression study on 1,500+ users that reframed a product team's entire roadmap.

AI features & agent systems: When do users trust AI to act on their behalf — and when does that trust break? I've researched this in clinical settings, productivity tools, and conversational agents. It's one of the most interesting research problems in tech right now.

International & cross-cultural research 8 countries. 5M+ users. Multiple languages. I design research that travels — building the insight frameworks and infrastructure that make findings usable across markets.
