Fourth year undergraduate Jerry Gao (BE ’23) is the latest student featured in 34th Street Magazine’s “Ego of the Week” series. Jerry, who hails from Coppell, TX, majors in Bioengineering with a minor in Asian American Studies. In addition to his academic studies, he is passionate about education and literacy, working with The Signal, the Asian Pacific American Leadership Initiative, and the Penn Reading Initiative. In this Q&A, he discusses the sense of community that brought him to Penn, the love of cooking (and gifting food to his friends) that powers his @gaos_chows Instagram account, and his experience as a student and now TA in Penn Bioengineering’s “BE MAD” lab class:
“Now that you’re on your way to graduating, what have been your favorite classes or experiences in Bioengineering or Asian American Studies?
‘In terms of bioengineering, there’s definitely a clear favorite that I have. It’s actually the class I’m a TA for right now. It’s “Bioengineering Modeling, Analysis, and Design,” and it’s basically the lab that all junior bioengineers take. There’s one particular lab we do in the class that always catches everyone’s attention; it’s called the cockroach lab. I think it’s one of the biggest reasons why people want to study bioengineering at Penn in particular.
It’s a segue into prosthetics and different medical devices that can help restore people’s limb functions. We order hundreds of cockroaches and then we put them in a little bit of an ice bath to anesthetize. We amputate their legs, which will essentially serve as our prosthetics, and then implant metal electrodes into two different spots of the leg. Then, we go into our computer program and type different lines of code that can help replicate different signal waves to move the legs. If you submit a wave with a particular frequency and particular amplitude, it’ll cause a leg to move in one direction, and if you do a different combination of the amplitude and frequency, it’ll cause it to move in the other direction. The next task is to trace the end of the leg and try to choreograph the leg to spell the letters B and E for bioengineering. It’s so fun to be able to see what combination of leg movements in the servo motor can form the backbone of the B for example, what can form the three lines of the E. I would say that’s probably my favorite moment in the bioengineering department.'”
