Biologist's work helps country control bird disease

Every summer, Mazhar Khan goes to Nanning, capital of the Guangxi Zhuang autonomous region in Southwest China, to spend a month or two.

And each time, the professor of pathology at the University of Connecticut is welcomed with a big reception in Nanning, which he says is like his second home.

Khan, 66, is a US citizen of Pakistani origin, and he was in Beijing on Sept 3 to witness the grand military parade marking the 70th anniversary of the end of World War II.
