Several of the departments on campus now organize mini-conferences around presentations by the grad students and/or faculty. EEMB has a faculty symposium in the Fall and a Grad student symposium in the Winter. This is coming up soon, Saturday Feb 12, and although it is free they do ask for people to register so they know how much coffee etc. to get (and you have to pay for dinner if you want feeding). Since I'm very keen that they have sufficient coffee I encourage you to register if you intend going.
This can be a great way to find out a lot about the research going on in a department. You really get a good sense of what graduate students do and you get to watch, and critique, a lot of talks in a short time. The agenda and abstracts are on the website but note that they do ask for you to sign up by the 1st Feb, Tuesday, tomorrow. It is certainly appropriate for undergraduates to go to this and there's usually a few CCS students there.
