Hi everyone! My name is Abigail Huebner and I’m a senior studying Bioengineering with a secondary in Mind, Brain and Behavior. I came into Harvard not planning on studying engineering and have found the engineering community and advising network to be so helpful, and I’m excited to pay that forward. I spent this past summer interning in medical devices at Medtronic and the previous summer doing research in the Harvard Biodesign Lab. Outside of engineering, I’m a peer counselor with ECHO (Harvard’s eating concerns-focused peer counseling group) and very involved with Harvard Hillel. As someone who didn’t decide on bioengineering until my sophomore year (or have research or engineering experience before then), I would love to talk about finding internship and research opportunities, choosing bioengineering and then choosing among all of the different bioengineering subtracks (there are so many options!), course selection, balancing engineering with non-engineering interests, and anything else!
