A 2008 Nobel laureate in chemistry will deliver two keynote speeches in Taipei to inaugurate a prestigious lecture series organized by Taiwan's leading academic institute, Academia Sinica, according to a press statement released Thursday by the institute.

According to the press release, Roger Yonchien Tsien will make a four-day visit to Taiwan Dec. 11-14. He will deliver the lectures, titled “Painting Cell Signals with a Palette of Fluorescent Proteins” and “Building Molecules to Image and Help Treat Cancer and Inflammatory Disease,” Dec. 11 and Dec. 14, respectively.

Tsien, a professor at the Chemistry and Biochemistry Department of the University of California, San Diego, was awarded the Nobel Prize with two other chemists -- Martin Chalfie of Columbia University and Osamu Shimomura of Boston University -- in recognition of their discovery and development of green fluorescent protein (GFP).

Commonly used in biology as a reporter of gene expression, Tsien and his co-winners made unprecedented contributions to the general understanding of how GFP fluoresces, extended the color palette beyond green, which allowed researchers to give various proteins and cells different colors, the press release said. “The discovery of GFP has led to its widespread use as a tagging tool in bioscience research.

By using DNA technology, researchers can now use GFP as a fluorescent marker to help better observe the movements, positions and interactions of tagged proteins,” it added.

Born in New York in 1952, Tsien graduated from Harvard University with a bachelor of science in chemistry and physics in 1972 and received his PhD in physiology from the University of Cambridge in 1977.

He comes from a line of top academics. His uncle Tsien Hsue-shen was a renowned rocket scientist regarded as the founding father of the Chinese ballistic missile.
