Woo's ancestral hometown is Yuyao, Ningbo, Zhejiang Province. Woo was born in 1937 in Shanghai, China. He fled the communist revolution in 1949 with his parents and came to the United States at the age of 18 from Hong Kong. He received undergraduate degrees in Mathematics and Physics from Georgetown College in Kentucky and his Ph.D. in Physics from Washington University in St. Louis.

He married Katy in 1963 and they have two children, Chi I. and Chi Lan. In 1966 he joined the faculty of the University of Delaware, where he became a professor of physics and astronomy. He retired in 2002 after 36 years.

In his first attempt at public office, Woo was elected Lieutenant Governor in 1984. He won the Democratic primary election by defeating two veteran State Senators, Nancy W. Cook of Dover and David B. McBride, of New Castle . In the general election he narrowly defeated Republican Battle R. Robinson of Georgetown , who was the first woman to practice law in Sussex County, and the assistant legal counsel to retiring Governor Pierre S. du Pont, IV. Woo thus became one of the highest ranking Chinese-American public office holder in the nation and served one term from January 15, 1985 until January 20, 1989.

Woo narrowly won the Democratic primary election for U.S. Senator in 1988, defeating Samuel S. Beard, an heir to a railroad fortune, and resident of Greenville , Delaware. In fact, the election appeared to be lost until an error in the tabulation was discovered, which changed the result. Nevertheless, Woo lost the general election to the incumbent Republican U.S. Senator William V. Roth, Jr.. Likewise, in 1992, he was the Democratic candidate for the U.S. House, but lost the election to retiring Governor Michael N. Castle.

Woo became an Independent in 2000 and announced his intention not to accept a federal appointment in order to advance public perception of his neutrality without any personal partisan benefit.

Woo is a leader in the greater Chinese American community throughout the country from whom his political activities dependably received strong financial backing. He is the past-president of the 80-20 Initiative, a group that attempts to organize Asian Pacific Americans (APAs) into a swing bloc-vote in presidential elections, intending to induce both major political parties to take the interests of the APA community into consideration. He also serves as a Trustee of the University of Delaware, an Institute Fellow at the Institute of Politics, the Kennedy School of Government, Harvard University.

A life-sized picture of him is displayed in Smithsonian's National Museum of American History in Washington D.C. Another picture of him is in an interactive display in the lobby of Asia Society in New York City. In 2000, A Magazine ranked him the 6th of the 25 Most Influential Asian Americans.

Elections are held the first Tuesday after November 1st. The Lieutenant Governor takes office the third Tuesday of January and has a four year term.
