AAAS is the world's largest scientific society and publishes the prestigious journal Science. Fellows are elected by their peers each year across 24 fields, from agriculture to anthropology to mathematics and medical science. It is a lifetime distinction.

The tradition of electing AAAS fellows began in 1874 to recognize members for their scientifically or socially distinguished efforts to advance science or its applications. The 2019 group will receive official certificates and rosette pins in gold and blue, colors symbolizing science and engineering, in a ceremony on Feb. 15, 2020, during the AAAS annual meeting in Seattle, Washington.
