Leon Ong Chua is an IEEE Fellow and a professor in the electrical engineering and computer sciences department at the University of California, Berkeley, which he joined in 1971.

Considered to be the "father of nonlinear circuit theory and cellular neural networks", he is also the inventor and namesake of Chua's circuit and was the first to conceive the theories behind, and postulate the existence of, the solid-state memristor. Thirty-seven years after he predicted its existence, a working solid-state memristor was created by a team led by R. Stanley Williams at Hewlett Packard.

A Chinese American, Chua and his fraternal twin sister grew up as members of the Chinese ethnic minority community in the Philippines under the reign of the Empire of Japan during World War II. He earned his BSEE degree from Mapúa Institute of Technology in the Philippines in 1959, then emigrated to the United States on a scholarship to the Massachusetts Institute of Technology, where he earned an MSEE degree in 1961. He then earned a Ph.D from the University of Illinois, Urbana-Champaign in 1964. His PhD thesis was entitled Nonlinear Network Analysis—The Parametric Approach. Over the ensuing years, he has received eight honorary doctorates.

Chua has four daughters; the eldest, Amy Chua (a Professor of Law at Yale University.), Michelle, Katrin (a professor at Stanford University), and Cynthia (Cindy).

Chua was a member of the faculty at Purdue University from 1964-1970 before joining Berkeley in 1971. His current research interests include cellular neural/nonlinear networks, nonlinear circuits and systems, nonlinear dynamics, bifurcation theory, and chaos theory. He is also the Editor of The International Journal of Bifurcation and Chaos.
