Duffy grew up in northern China. He attended the top Chinese film school and had a career with CCTV before moving to the US. In San Francisco, he began working for a local PBS affiliate producing and directing programming. When the channel was bought about 15 years ago, he launched D3 Productions to create original documentaries about China for the PBS audience. His 2007 film Sketching the Silk Road won an Emmy. Duffy’s mission: help Americans learn about the rich layers of Chinese culture that never make it to the news.
