Rosalyn Sussman Yalow

Rosalyn Sussman Yalow was a pioneering American medical physicist who won the Nobel Prize in Physiology or Medicine in 1977 for her development of the radioimmunoassay (RIA) technique. This innovative method allows scientists to measure tiny concentrations of hormones and other substances in the blood, greatly advancing medical diagnostics. Her work relied on principles of crystallography to understand molecular structures, leading to breakthroughs in detecting diseases. Yalow's contributions have had a lasting impact on research and health care, enabling more precise and earlier diagnoses of various conditions. She was also a trailblazer for women in science.
