Leon Ong Chua(/ˈtʃwɑː/;Chinese:Thái thiếu đường;pinyin:Cài Shǎotáng;Wade–Giles:Ts'ai Shao-t'ang;Pe̍h-ōe-jī:Chhòa Siáu-tông;born June 28, 1936) is an Americanelectrical engineerandcomputer scientist.He is a professor in the electrical engineering and computer sciences department at theUniversity of California, Berkeley,which he joined in 1971. He has contributed tononlinearcircuit theoryandcellular neural networktheory.[2]

He is the inventor and namesake ofChua's circuit[3]one of the first and most widely known circuits to exhibitchaoticbehavior, and was the first to conceive the theories behind, and postulate the existence of, thememristor.[4]Thirty-seven years after he predicted its existence, a working solid-state memristor was created by a team led byR. Stanley WilliamsatHewlett Packard.[5][6]

AlongsideTamas Roska,Chua also introduced the first algorithmically programmable analogcellular neural network(CNN) processor.[7]

Early life and education[edit]

A first-generation Filipino-Chinese-American, Chua and his twin sister grew up as members of theHokkienChinese ethnic minorityin thePhilippines[8]under the reign of theEmpire of JapanduringWorld War II.OfHokloancestry, his parents immigrated fromJinjiang,Southern Fujianprovince.[9]In 1959, he earned his BSEE degree fromMapúa Institute of TechnologyinManila,Philippines. He briefly taught at Mapúa for a year,[10]before emigrating to theUnited Stateson a scholarship to theMassachusetts Institute of Technology,where he earned an MSEE degree in 1961. He then earned aPh.D.from theUniversity of Illinois, Urbana-Champaignin 1964. His PhD thesis was entitledNonlinear 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 atYale University[8]), Katrin (a Professor of Medicine atStanford University), Cynthia (Cindy, a SpecialOlympics Gold medalist), and Michelle (a Yale Law School graduate). In addition to his four daughters, Chua has seven grandchildren.[11][12]

Career[edit]

Chua was a member of the faculty atPurdue Universityfrom 1964 to 1970 before joining Berkeley in 1971. His current research interests includecellular neural networks,nonlinear networks, nonlinear circuits and systems,nonlinear dynamics,bifurcation theory,andchaos theory.He was the editor ofThe International Journal of Bifurcation and Chaos[13]until 2009, and is now the honorary editor.
