Biography

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 my Masters degree in 2018 from the University of St Andrews advised by Vivienne Wild.

My research focuses on the stellar mass assembly of galaxies in the early universe through observations 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), and UNCOVER. I also co-lead the Lyman Break Galaxy Work Package for the Euclid Consortium and coordinate US-Euclid high redshift teams.

I have held internship or visiting positions at the California Institute of Technology, the University of Hawaii, the Max-Planck Institute for AstronomyLeiden 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.
