UX Research Lead · Developmental Psychologist

I turn how people behave into things that fit their lives.

For ten years I led research at Google, shaping Gmail, Calendar, and Tasks for more than a billion people. My training is in child development, and that's still the lens I bring to my work. Today I help parents make sense of what's behind their kids' behavior, and I help teams build products that feel obvious to the people using them.

For parents

Understand your child's behavior, calmly and with the science behind it.

I take what developmental research actually says and turn it into calm, practical guidance you can use at home. More than 10,000 parents follow along on TikTok, Instagram, and YouTube, learning to read their kids' behavior instead of just reacting to it.

For teams

Research leadership, strategy, and mentoring.

Ten years leading UX research at Google, across productivity tools and AI. I'm good at getting stakeholders aligned, running research that mixes methods, and turning what we learn into decisions teams actually act on. I also mentor researchers, and I'm open to consulting, speaking, and advisory work.

About

A researcher who reads people for a living.

I'm a research leader with a background in child development and ten years at Google behind me. My job has always come down to the same thing: watch how people really behave, whether they're office workers, executives, or families, and use that to build things that fit their lives. Along the way I helped shape strategy for tools used by more than a billion people.

I've also mentored eight researchers into full-time roles, which I'm quietly proud of. These days I spend my time helping parents make sense of their kids' behavior, bringing the same rigor I used on billion-user products to the questions that matter most at home.

Selected work

Research that shipped to a billion people.

Google Calendar

2019 – 2026

When COVID hit, I ran the research that let Calendar respond fast. It fed straight into the hybrid-work features people rely on today: Working Location, Focus Time, and Time Insights. The work drew on feedback from 26 of our top enterprise customers and more than 400 power users. I also facilitated Calendar's first hybrid design sprint, getting around 25 partners aligned on a three-year plan.

Google Tasks

2018

I led the research behind the very first Tasks mobile app, from the early studies through launch, and took the findings and success metrics straight to VPs. Focus groups with top UK enterprise customers helped shape where the product went next.

Gmail

2015 – 2017

I built a readiness-to-launch framework that shaped Smart Reply across four languages, one of which Google's CEO called out on an earnings call. My diary studies into how people actually write also informed early Smart Compose and the writing help that came after it.

Waymo

2013 – 2015

I led the ergonomics and human-factors research on prototype self-driving cars, which shaped both the in-car experience and the safety decisions behind it. I ran usability studies for the rider app, and led ride-alongs and empathy sessions with participants who were visually or mobility impaired, alongside C-level executives.
