Biography
Linda Brown Buck was born on January 29, 1947, in Seattle, Washington. She did her undergraduate studies at the University of Washington before getting her Ph.D. from the University of Texas Southwestern Medical Center. Her doctoral research focused on the immune system, but she later shifted to studying neuroscience and how smell and taste work.
Buck's important research began during her postdoctoral work at Columbia University in Richard Axel's lab. Together, they aimed to understand how the olfactory system works at the molecular level. In 1991, they published a key study identifying a large family of genes responsible for olfactory receptors, solving a major mystery about how mammals detect and distinguish thousands of odors. Their research showed that about 1,000 different genes are responsible for olfactory receptors in mice, which makes up about 3% of all mammalian genes.
Working with Axel laid the groundwork for how we understand olfactory transduction today. Buck found that each olfactory receptor neuron expresses only one type of receptor protein and that neurons with the same receptor send signals to the same brain area. Her work explained how the nose can detect a wide range of chemical compounds and how the brain processes this to create the sense of smell.
Buck continued her research at Harvard Medical School before joining the Fred Hutchinson Cancer Research Center in Seattle, where she expanded her studies on neural circuits related to smell. Her lab has investigated how the brain processes olfactory information and how it affects behavior and memory. In 2004, Buck and Axel won the Nobel Prize in Physiology or Medicine for their discoveries about the olfactory system and odorant receptors.
Throughout her career, Buck has won many major awards, including the Canada Gairdner International Award in 2003, the Rosenstiel Award in 1996, and the Perl-UNC Prize in 2002. She was elected a Fellow of both the American Association for the Advancement of Science and the American Academy of Arts and Sciences, and became a Foreign Member of the Royal Society in 2015. Harvard University gave her an honorary doctorate in 2015. Buck is married to Roger Brent, who is also a scientist and researcher.
Before Fame
Buck grew up when scientific opportunities for women were growing but still limited. She attended Roosevelt High School in Seattle and then went on to higher education just as major advances were being made in molecular biology and genetics. The 1960s and 1970s brought important breakthroughs in understanding DNA, protein synthesis, and cellular mechanisms.
Her early academic journey showed the mixed nature of modern biology, as she shifted from immunology to neuroscience. Neurobiology was advancing quickly during her training, with new techniques in molecular biology allowing researchers to explore previously unanswered questions about brain function and sensory systems.
