Roger Y. Tsien

Roger Y. Tsien was an American biochemist renowned for his pioneering work in the field of molecular biophysics, particularly in developing fluorescent proteins. He played a vital role in advancing our understanding of cellular processes by creating tools that illuminate specific proteins within cells, making them visible under a microscope. His most famous contribution, the discovery and development of the green fluorescent protein (GFP), revolutionized biological research, allowing scientists to track proteins and study disease mechanisms in real-time. Tsien's work has had a profound impact on biology, medicine, and biotechnology, earning him the Nobel Prize in Chemistry in 2008.
