'''Elizabeth J. Tasker''' (born 12 July 1980) is a British astrophysicist and science writer.

Tasker is currently an associate professor at the Japan Aerospace Exploration Agency and is highly active in science communication. Her first book, ''The Planet Factory'', was published by Bloomsbury in 2017.

== Early life and education == Tasker graduated from Durham University in 2002 with a MSci in theoretical physics.<ref>{{cite web |title=Curriculum Vitae |url=https://www.elizabethtasker.com/research |website=Elizabeth Tasker |access-date=20 April 2019 |archive-date=20 April 2019 |archive-url=https://web.archive.org/web/20190420013650/https://www.elizabethtasker.com/research |url-status=dead }}</ref> As an undergraduate, she won the 1999 ''The Daily Telegraph'' Young Science Writers Award.<ref name="Bloomsbury profile" />
