Hihi, this is Junchao! People also call me David!

I am a strategic researcher in practice and a storyteller & media artist in heart, who specializes in participatory design and tackles research with system thinking. I help businesses and product teams make user-centered and socially responsible decisions.

I have over 5 years of experience conducting mixed-method UX and design research in academia and the industry. Currently, I am leading research strategy for Security and Operational Technology business units at ServiceNow as a Sr. UX Researcher, covering more than 6 products. Previously, I was leading research for the China team and the Duolingo English Test team at Duolingo.

I used to work with Dr. Laura Dabbish at Carnegie Mellon University Human-Computer Interaction Institute’s CoEx Lab as a full-time HCI researcher. I was leading the NSF-funded research on account-sharing behaviors in romantic couples. My research works were published at CHI and CSCW, the top HCI conferences.

In my spare time, you can find me 🚴🏼, 🥾, 🎾, 🏸, ⛹🏼‍♂️, 🏊🏼‍♂️, 99.9 % chance outdoors!

I also enjoy making art such as Chinese calligraphy, Chinese Shuimo painting, and taking photos.
