STudent REsEarch TalkS

The Student Research Talks (StReeTs) at George Mason University is a student-run seminar, overseen by benevolent leader Prof. Sean Lawton. Its purpose is to give graduate and advanced undergraduate students a forum to discuss research and other topics of interest as well as the opportunity to practice giving talks to colleagues. All students are welcome to attend. If you would like to present a topic please contact one of the organizing committee members (Kelsi Listman and Nat Fink-Humes).

Time and location:

Fridays 2:30-3:20 pm, Exploratory Hall room 4106
