Special Lecture by Nobel Prize Laureate in Chemistry, Dr. Martin Chalfie On May 29th, Novel Prize laureate in Chemistry, Dr. Martin Chalfie of Columbia University delivered a special lecture at Yonsei Samsung Library. Dr. Chalfie was awarded the Nobel Prize in Chemistry in 2008—with Dr. Osamu Shimomura, Professor at the College of Medicine at Boston University and Woods Hall Marine Biological Laboratory, and Dr. Roger Y. Tsien, Professor at the Department of Chemistry and Biochemistry at University of California, San Diego—in recognition of their contributions to the discovery and development of Green Fluorescent Protein (GFT) in multicellular organism like jellyfish. In his lecture, Dr. Chalfie explicated with GFP those phenomena in the living organism that were unable to be observed, such as how cell nerves grow and how cancer cells spread out. In an organism, GFP takes on a signaling role, which enables the examination of how proteins move about and interact.
