The laboratory has identified some TCM components that might be used for the treatment of leukemia and other kinds of cancer, and a few relevant drugs are in pre-clinical development, he says.

In addition to drug discovery, Ben-David's team is also engaged in uncovering the molecular mechanism of cancer progression.

In collaboration with local scientists, they are working on understanding the molecular cause of diseases specific to the province.

Ben-David has also taken advantage of his wide network of contacts to help Guizhou enhance its international exchanges, including bringing top scientists for conferences.

Ben-David, who lives in Guiyang, says he enjoys life in the city despite the distance between the laboratory and the city center.

Having completed his first three years at the laboratory, Ben-David has just renewed his contract for another three.

Ben-David, who has married Yao Shaojuan, a local woman, is learning Chinese and says he plans to stay in China for a long time.
