Yu-Chi Lin

Engineer running on the track.



Yu-Chi Lin is a third-year Ph.D. student, working with Prof. Ali Niknejad and Prof. Kris Pister, at Berkeley Wireless Research Center (BWRC) and Berkeley Sensor & Actuator Center (BSAC), Electrical Engineering and Computer Sciences department (EECS), at University of California, Berkeley. Her research focuses on mixed-signal IC, biomedical sensor, system-on-chip (SoC), and mm-Wave IC. Her goal is to apply IC design and mm-Wave to human healthcare and brainstorm engineering approaches to benefit people worldwide.

Yu-Chi Lin comes from Taiwan. She graduated with the highest distinction, Dr. I-Chi Mei Memorial Medal (7 out of 2000 in class 2021) from the department of Electrical Engineering (NTHUEE) (ranked 1/102), National Tsing Hua University (NTHU), Hsinchu, Taiwan, in June 2021. She is the recipient of Taiwan-UC Berkeley Fellowships (top 5 UC Berkeley Ph.D. students from Taiwan), 2022 & 2023 ISSCC Student Travel Grant Award (STGA), and 2022 IEEE SSCS Next Generation Circuit Designer.

Fun Fact

Yu-Chi is an engineer running on the track!

Yu-Chi was a middle-distance, 800M, track-and-field school representative at National Tsing Hua University (October 2018 ~ June 2021). She was not a professional athlete, but she enjoys training and running!

Outside of work, Yu-Chi enjoys jogging, swimming, going to the gym, exploring nature, and making friends!

May 2023, body weight journey started.
