Allan C. Spradling

Allan C. Spradling is an American scientist and principal investigator at the Carnegie Institution for Science and the Howard Hughes Medical Institute who studies egg development in the model organism, Drosophila melanogaster, a fruit fly.^[2] He is considered a leading researcher in the developmental genetics of the fruit fly egg and has developed a number of techniques in his career that have led to greater understanding of fruit fly genetics including contributions to sequencing its genome.^[2] He is also an adjunct professor at Johns Hopkins University and at the Johns Hopkins University School of Medicine.^[2]

Education

Spradling obtained an A.B. in physics from the University of Chicago. He earned his Ph.D. in cell biology from the Massachusetts Institute of Technology in 1975 and completed a postdoctoral fellowship at Indiana University.^[2] He joined Carnegie Institution for Science in 1980 and served as the director of the organization’s former Department of Embryology between 1994 and 2016.

Career

Spradling and fellow American geneticist Gerald M. Rubin are considered pioneers in the field of genetics for their work in the early 1980s with their idea to "attach" a gene to a Drosophila transposon, P elements,^[3] known to insert itself into fruit fly's chromosomes.^[4] From this research came work from other scientists on transposons as a tool for genetic alterations in organisms.^[4][5][6][7]

In 2003 Spradling was awarded the Beadle Medal^[1] and in 2008 Spradling was awarded the Gruber Prize in Genetics for his work on the Drosophila genome and continues his work in investigating novel technological approaches to genetics, egg development and stem cells. He was elected to the American Philosophical Society in 2016.^[8] In 2024 he received the Wiley Prize.^[9]
