Yuyi Shen’s Personal Projects and Work

Hiya! I’m a graduate of Prof. Vanessa Chen’s research group (Energy-Efficient Circuits and Systems Lab) at Carnegie Mellon University, Pittsburgh, PA, USA. I received my Ph.D. in Electrical and Computer Engineering in Aug. 2024. My research focused on the application of analog RF circuits to wireless security and operation under cryogenic temperatures. I’m currently doing a working holiday in Australia after checking out British Columbia and Scotland. You can check out a list of my publications below along with some links to my personal projects.

Freddy is my fluffiest friend. Two of my brain cells are on indefinite loan to this loaf for operating his tail (pitch and yaw).

Junior is the latest addition to the family! Extraordinarily naughty and always wants his food right meow.
