Yuanfeng Gao, Ph.D., is a student associate in Sterne Kessler’s Electronics Practice Group. Yuanfeng is experienced in drafting and prosecuting patent applications utilizing a wide range of electrical technologies. He also assists in litigation matters at the Patent Trial and Appeal Board. Yuanfeng has particular expertise in semiconductor devices, photolithography systems, thin film growth/characterization, microfabrication techniques, superconducting material and devices, and cryogenic systems.

Yuanfeng received his M.S. and Ph.D. in physics from the University of Wisconsin – Madison. His doctoral research focused on low-loss superconducting quantum bits. He was directly involved with designing and fabricating Josephson phase qubits incorporating crystalline silicon nanomembrane, superconducting through-silicon vias, and microwave resonators with low-loss dielectric material. He also has seven years of microfabrication experience, including hands-on experience with material deposition/etching and photolithography processes. He is a member of the American Physical Society and IEEE.

Yuanfeng earned his B.S. in microelectronics from Nankai University in Tianjin, China and is currently a J.D. Candidate (2020) at the Antonin Scalia Law School, George Mason University.
