Alexandra Lee Jessica Freeman, Baroness Freeman of Steventon (born March 1974) is a British science communicator, life peer, and former television producer. She has been a crossbench member of the House of Lords since 2024, and principal of Hertford College, Oxford since March 2026.

Biography Freeman was born in March 1974 in Maryland, United States. Her mother is a theoretical physicist, her father trained as a chemist, and her sister is a mathematician. She studied biological sciences with biological anthropology at New College, Oxford, graduating in 1995 with a Bachelor of Arts (BA) degree.

In 2016, Freeman joined the University of Cambridge as executive director of the Winton Centre for Risk and Evidence Communication in the Faculty of Mathematics.

In 2018, Freeman proposed a new approach to scientific publishing in the form of the Octopus platform designed to publish "smaller units of publication" and to promote the principles of open science. In 2021, Octopus received a grant from Research England to develop the platform into a global service.
