My name is Jeffrey Sullivan. I am a twenty-something engineer living in Quincy, Massachusetts. I am currently employed by Massachusetts General Hospital as a linear accelerator engineer. I have an undergraduate degree in physics from Eastern Nazarene College. However, there are plenty of Wikipedia users with physics knowledge to keep the physics accurate, so most of my contributions are grammatical. I also do a lot of web surfing, so I provide and correct external links in Wikipedia articles from time to time.
