Andrew (Drew) David Endy (born 1970) is a synthetic biologist and tenured associate professor of bioengineering at Stanford University, California.

[14] Endy is one of several founders of the Registry of Standard Biological Parts, and invented an abstraction hierarchy for integrated genetic systems.

Endy headed a team of researchers that in March 2013 created the biological equivalent of a transistor, which they dubbed a "transcriptor".

The invention was the final of the three components necessary to build a fully functional biocomputer: data storage, information transmission, and a basic system of logic.

[18] Endy is a founder and steering group member of the Build-a-Cell Initiative, an international collaboration investigating creation of synthetic live cells.
