Removing Forced Decisions Increased Engagement Without Reducing Connection Success

2.6× more profile views • 2.1× more sessions • +22% chat conversion • +18% profile visits/session

An A/B test followed by 120-day telemetry validation showed that free browsing increased exploration and chat conversion without reducing total connections.

Prioritizing Profile Features Using MaxDiff Tradeoff Modeling

16+ weeks of development saved • 115 participants • 1,035 best-worst evaluations • 12 profile attributes modeled

A controlled MaxDiff study quantified a stable feature hierarchy, showing that foundational identity signals consistently outperformed rich media profile features.

Improving Discoverability Through Home Page Design

+44% sessions reaching profiles • +45% connection acceptance • 30-day post-launch evaluation

A log-level behavioral analysis identified suppressed exploration within the home feed, leading to a redesign that improved profile discovery and connection outcomes.

Reducing Onboarding Friction Through Progressive Profile Completion

~70% faster onboarding (~11 min → ~3 min) • 900+ users observed • 54 hours of field research

Usability testing showed that users were asked for too much before experiencing value, leading to a faster onboarding flow with progressive profile completion.

About

I am a UX researcher and product strategist with a PhD in Cognitive Psychology from UCLA. My work explores how people perceive, behave, and make decisions under uncertainty, translating behavioral research into products that are intuitive, measurable, and grounded in evidence.


Across startups, connected hardware, and academic research, I have combined qualitative research, controlled experimentation, behavioral analytics, and computational modeling to understand user behavior and guide product strategy. Whether redesigning social discovery systems, improving fleet operations, or modeling visual perception, my work begins with understanding behavior and ends with clear, testable product decisions.


I enjoy working on complex systems where behavior emerges from the interaction between people, technology, and context. My goal is to transform ambiguity into structure by identifying meaningful patterns, evaluating competing ideas, and translating research into products that are both useful and scalable.
