Enrico Sandro Coen CBE FRS (born 29 September 1957) is a British biologist who studies the mechanisms used by plants to create complex and varied flower structures.

In 1982, he earned a PhD for research on Drosophila supervised by geneticist Gabriel Dover on the evolution and function of genes needed to make ribosomal RNA in fruit fly lines, which were selected for the number of bristles on their abdomen.

After a year (1983/4) he sought a different plant system to continue his research at John Innes Centre in Norwich which studied Antirrhinum, commonly known as snapdragon, and was hired together with colleague Cathie Martin to join the lab of Brian Harrison and Rosemary Carpenter.

[2] In collaboration with Elliot Meyerowitz of the California Institute of Technology he created computer simulations of how plant cells and their genes interact to direct flower formation and control colour.

[6] In 1994 he published evidence of unity and logic of floral development across species on the molecular level as did the labs of Meyerowitz, of Zsuzsanna Schwarz-Sommer and Hans Sommer at Max Planck Institute in Cologne.
