Chung-Mo Kwok, a computer programmer and political blogger who had taught mathematics at universities around the world, died Jan. 10 at Reston Hospital Center. He was 71.
Dr. Kwok, a resident of Bethesda, Md., was driving erratically on the Dulles Toll Road near Dulles International Airport while going to pick up his wife. He was stopped by an FBI agent, who alerted the airport police. He had a heart attack on the toll road and was pronounced dead at the hospital, said his wife, Shay-Whey Koh.
Chung-Mo Kwok was born in Shaoguan, China. He was a 1964 mathematics graduate of the California Institute of Technology and received a doctorate from Columbia University in 1969.
He became an assistant professor at Adelphi University in Garden City, N.Y., in 1970. He later worked at universities in Vancouver, B.C.; Shiraz, Iran; the West Bank; and Kano, Nigeria.
In 1984, he moved to Bethesda and began work as a computer programmer and consultant at companies such as SAIC.
Dr. Kwok left computer programming in 2003 to start writing a column under the pseudonym Duren for the Singapore-based newspaper Lianhe Zaobao. He used the same pen name when he started a political blog in 2008. In 2005, he started working as a substitute teacher for Montgomery County public schools.
Survivors include his wife of 29 years, Shay-Whey Koh of Bethesda; a son, Siwei Kwok of Los Angeles; a brother; and a sister.
