I am a member of the Imperial JUNO committee. I am passionate about making academia a more pleasant environment for everyone. I am co-director of The 1752 Group, a campaign group tackling sexual misconduct in higher education.


I have written a popular science book on the subject of the first stars, published by Bloomsbury Sigma in November 2020. Order here
