Leon Ong Chua IPA|/ˈtʃwɑː/ (zh-c|c=蔡少堂; born June 28, 1936) 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 [" Dr. Leon O.

Early Life and Education

Chua and his fraternal twin sister grew up as members of the Han Chinese ethnic minority community in the Philippines"Among the Chuas, the pronoun 'we' was a bicultural portmanteau — it meant both 'we Han Chinese' and 'we Americans.'" cite web|url=http://www.nytimes.com/2007/11/18/books/review/morrow.html?pagewanted=print|title=How to Rule the World|author=Lance Morrow|date=2007-09-18|publisher=New York Times] 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.

Career

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.
