Astrophysicist researching the impact of galaxy environments on type Ia supernova cosmology. Co-creator of the Kilonova Seekers citizen science project, and co-lead of science communication for 4MOST.

Postdoctoral Affiliate, Newnham College

I am an astrophysicist at the University of Cambridge working on type Ia supernovae and their host galaxy environments. My current Leverhulme Early Career Fellowship uses data from my Hubble Space Telescope program to study supernova siblings, pairs of supernovae in the same galaxy that let us disentangle local and global environmental effects.

Alongside my core research, I co-created Kilonova Seekers, a citizen science project where volunteers help discover transient events in real time, and I co-lead science communication for the 4MOST spectroscopic survey. I am a member of the Dark Energy Survey, GOTO, 4MOST, and Rubin LSST collaborations.
