Research occurs year round at Olin. During the school year many students engage in part time research for pay or for credit. Over the summer there are many full (and part) time positions available on campus, and lots of students stay in the dorms to participate.
A great way to learn about all the research that Olin has to offer is by attending the annual research fair! This event is less formal than a career fair; you won't need to bring a resume and semi-casual attire is appropriate. Show up with lots of curiosity and questions, and make sure to follow up with any professors you are interested in working with after the fair.
Another way to learn about research is to reach out to faculty directly. This might be a professor whose class you enjoyed, or one you've never met who leads a project you are interested in. If you are unsure how to reach out, start with a short, professional email introducing yourself and explaining why you are reaching out.
The National Science Foundation funds a large number of research opportunities for undergraduate students through its REU Sites program. An REU Site consists of a group of ten or so undergraduates who work in the research programs of the host institution. Each student is associated with a specific research project, where they work closely with the faculty and other researchers. Students are granted stipends and, in many cases, assistance with housing and travel. Undergraduate students supported with NSF funds must be citizens or permanent residents of the United States or its possessions. An REU Site may be at either a US or foreign location.
