One of the best things a graduate student can do is talk to other scientists. Doing so, they learn about new techniques, incorporate approaches from other fields, and refine ideas. At MIT there’s a culture of collaboration and multidisciplinary research. A lot of the best ideas I’ve had come from talking to my labmates and leveraging their knowledge. You can read as many reviews as you want but nothing beats talking to a person who understands a different field to give you that perspective.
