Broad Experience Made the Difference
Aravind Uthaman, ME’19, civil engineering, was crawling on his hands and knees for more than 300 feet into a water conduit tunnel. It was certainly not a position he expected to be in when graduated in 2019 with a master’s degree in structural engineering. But then again, Northeastern students pride themselves on being able to […]
