Nick Mathewson is an American computer scientist and co-founder of The Tor Project. He, along with Roger Dingledine, began working on onion routing shortly after they graduated from Massachusetts Institute of Technology (MIT) in the early 2000s. He is also known by his pseudonym nickm. Mathewson and Dingledine were the focus of increased media attention after the leak of NSA's highly classified documents by Edward Snowden, and the subsequent public disclosure of the operation of XKeyscore, which targeted one of The Tor Project's onion servers along with Mixminion remailer which are both run at MIT.
