In 1980, Buck began
postdoctoral research at Columbia University under Benvenuto Pernis (1980–1982). In 1982, she joined the laboratory of Richard Axel, also at Columbia in the Institute of Cancer Research. After reading Sol Snyder's group research paper at
Johns Hopkins University, Buck set out to map the olfactory process at the molecular level, tracing the travel of odors through the cells of the nose to the brain. Buck and Axel worked with rat genes in their research and identified a family of genes that code for more than 1000 odor receptors and published these findings in 1991. Later that year, Buck became an assistant professor in the
Neurobiology Department at
Harvard Medical School where she established her own lab. After finding how odors are detected by the nose, Buck published her findings in 1993 on how the inputs from different odor receptors are organized in the nose. Essentially, her primary research interest is on how
pheromones and
odors are detected in the nose and interpreted in the brain. She is a Full Member of the Basic Sciences Division at
Fred Hutchinson Cancer Research Center, and an Affiliate Professor of
Physiology and
Biophysics at the University of Washington, Seattle. == Nobel Prize in Physiology or Medicine (2004) ==
