Hubble Ultra Deep Field | NASA, ESA, and F. Summers
I am a Postdoc based at the University of Massachusetts Amherst in Kate Whitaker’s Group. I received my PhD in 2022 from the Cosmic Dawn Center advised by Sune Toft, and before that my Masters degree in 2018 from the University of St Andrews advised by Vivienne Wild. My research focuses on the stellar mass assembly of galaxiesand star-formation cessation in the early universe through direct observation with telescopes from both space and the ground. I am a core member of several collaborations including the Cosmic Dawn Survey (DAWN), Cosmic Evolution Survey (COSMOS), UNCOVER, as well as the Euclid Consortium.
I have held internship or visiting positions at the California Institute of Technology, the University of Hawaii, the Max-Planck Institute for Astronomy, Leiden Observatory, and the Maria Mitchell Observatory. I also led the creation of the spectroscopy database AVSpec for the American Association of Variable Star Observers as a Mayall Fellow.
Beyond academia, I am a frequent contributor to popular science publications including the paper digest Astrobites, and have been a long-time volunteer at public observatories.

I began my career in astronomy as an assistant to a planetarium lecturer. Giving back to the community is a part of who I am.
Astronomy on Tap – Copenhagen is a monthly event held at Huset, organised by astronomers in Copenhagen.
Crisp evening air. Clear skies. Maybe a telescope. Nothing refreshes me more than a night under the stars.
