Sin Lee Loh

UX Researcher

I am a researcher who was born and raised in Malaysia but am now based in California after earning my M.S. in Human Factors and Ergonomics from San Jose State University. I joined Facebook in 2015 as a User Experience Researcher and I support the Facebook Marketplace team using a variety of research methods to help understand and facilitate buying and selling activities on Facebook. Prior to Facebook, I was a researcher for eBay focused on shopping experiences. I’m a strong believer of collaborative and multi-method research methods, and love involving real user data to inspire, innovate and drive product experiences.
