About me

Hi! I'm Claudia. I grew up in Hong Kong, and currently live in Chicago, Illinois, in the USA. My research interests are online social interaction, particularly online community moderation. Sometimes, I provide voiceover.

My hobbies include calligraphy, cooking and conlanging. My private account is User:Cwylo. In addition to whatever my Babel box says, I'm also a passive speaker of Cantonese.

My work

I work as a Senior Design Researcher, with the Moderator Tools and the Trust and Safety Product teams. I was a staff member on the Universal Code of Conduct Drafting Revisions Committee.

Disclaimer: I work for or provide services to the Wikimedia Foundation, and this is the account I try to use for edits or statements I make in that role. However, the Foundation does not vet all my activity, so edits, statements, or other contributions made by this account may not reflect the views of the Foundation.
