Ke Wu (born 9 December 1962) is a professor and researcher in electrical engineering. He currently works at the Ecole Polytechnique^[1][2] in Montreal, and is a Tier-I Canada Research Chair^[3] in radio-frequency (RF) and millimetre-wave engineering.

He is active in the following areas of research: microwave and millimeter wave (components, devices, receiver/transmitter); characterization and measurement of dielectric materials; fast electronics (fast logic circuits, interconnects); superconductors (circuits, applications); numerical modeling (CAD, electromagnetic fields); and optoelectronics (photonics components, broadband transmission).^[4]

Wu is the director of the Poly-Grames Research Center,^[4] founding director of the Canadian university-industry consortium, Facility for Advanced Millimetre-wave Engineering and the Center for Radiofrequency Electronics Research of Quebec.^{[clarification needed]} He was elected an IEEE Fellow in 2001.^[5]

In 2020, the National Post published an article stating that Wu is also a researcher at several universities in China, with at least one position being full-time; the National Post also noted that he had in 2011 been a delegate to the Chinese People's Political Consultative Conference (CPPCC), and an advisor to the Overseas Chinese Affairs Office of the Chinese Communist Party's United Front Work Department.^[1] Wu subsequently objected to suggestions that he had a parallel academic career in China, calling them "absolute nonsense", and stated that his students would often add his name to other projects exaggerating his role in order to obtain funding.^[6] He also said that his role with the CPPCC had been as an "observer".^[6]
