Bassler is a Howard Hughes Medical Institute Investigator and professor and chair of the department of molecular biology at Princeton University. Her lab focuses on quorum sensing, a process that allows bacteria to communicate using chemical signaling. Quorum sensing enables groups of bacteria to regulate gene expression, resulting in changes in behavior on a population-wide scale. 

Among her many honors, Bassler is a member of the National Academy of Sciences, the National Academy of Medicine, the Royal Society, the American Philosophical Society, the American Academy of Arts and Sciences and she is a fellow of the American Association for the Advancement of Science.

She is a recipient of Princeton University President’s Award for Distinguished Teaching, the Wolf Prize in Chemistry, the Canada Gairdner International Award, the Princess of Asturias Award from the Spanish Crown, the Gruber Prize in Genetics, the Albany Prize in Medicine, the L’Oréal–UNESCO Women in Science Award and a MacArthur “genius grant.” Bassler was formerly the President of the American Society for Microbiology and the chair of the American Academy of Microbiology Board of Governors. 

“I am delighted and honored to receive the National Medal of Science,” Bassler said. “Most moving and memorable to me were the speeches at the ceremony. They were not about a scientist being the best in a field, nor the first to make a revolutionary finding, but rather, about the importance of the recipients’ research and mentorship of the next generations of scientists to democracy and to the vitality of and possibilities for the nation now and going forward.”

The National Medal of Science was established in 1959 and is administered for the White House by the National Science Foundation. The medal recognizes individuals who have made outstanding contributions to science and engineering.
