Hello I'm Julia and welcome to my crib ;)
This website contains a lot of information about SEAS at George Washington, including events, opportunities for undergraduates, alumni and faculty, and even how to apply. You can find almost anything you need here, and it even gives the contact information for many important faculty at SEAS.
On this website you can find information that is much more specific to Computer Science at GW. For example, there are a lot of resources for computer science research, information about the faculty, and news about the department.
