About

Hello, my name is Tavis Ormandy, I’m a vulnerability researcher with Google Project Zero. I’m originally from England, but I currently live in the San Francisco Bay Area.

You’re probably interested in some of my vulnerability research, or perhaps some code I’ve written.

I sometimes tweet about what I’m working on.
