Leon Ong Chua (/ˈwɑː/; Chinese: 蔡少棠; pinyin: Cài Shǎotáng; Wade-Giles: Ts'ai Shao-t'ang; Pe̍h-ōe-jī: Chhòa Siáu-tông; born June 28, 1936) is a Chinese-American electrical engineer and computer scientist. He is a professor emeritus of electrical engineering and computer science at the University of California, Berkeley, which he joined in 1971. He has contributed to nonlinear circuit theory and cellular neural network theory and is recognized as the "Father of Nonlinear Circuit Theory" or electronic devices from nonlinear components.

He is the inventor and namesake of Chua's circuit one of the first and most widely known circuits to exhibit chaotic behavior, and was the first to conceive the theories behind, and postulate the existence of, the 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.

Alongside Tamas Roska, Chua also introduced the first algorithmically programmable analog cellular neural network (CNN) processor.

01Early life and education

Chua was born in the Philippines on June 28, 1936, to a Hoklo Chinese family. He and his twin sister grew up as Chinese Filipinos under the reign of the Empire of Japan during World War II. His parents immigrated from Jinjiang, Southern Fujian.

In 1958, Chua earned his BS in electrical engineering from the Mapúa Institute of Technology in Manila, Philippines. He briefly taught at Mapúa for a year, before emigrating to the United States on a scholarship to the Massachusetts Institute of Technology, where he earned an MS in electrical engineering degree in 1961. He then earned a PhD from the University of Illinois, Urbana-Champaign, in 1964. His dissertation was titled, Nonlinear Network Analysis, The Parametric Approach.

Chua has four daughters: Amy Chua (the eldest), a professor of law at Yale University; Katrin, a Professor of Medicine at Stanford University; Cynthia, a Special Olympics gold medalist; and Michelle, a Yale Law School graduate. In addition to his four daughters, Chua has seven grandchildren.

02Career

Chua was a member of the faculty at Purdue University from 1964 to 1970 before joining Berkeley in 1971. His current research interests include cellular neural networks, nonlinear networks, nonlinear circuits and systems, nonlinear dynamics, bifurcation theory, and chaos theory. He was the editor of The International Journal of Bifurcation and Chaos until 2009, and is now the honorary editor.
