Alexandra Masegian

I’m a first-year PhD student in astronomy at Columbia University, with broad interests in stellar astrophysics. Topics that I find especially interesting include massive stars, binaries and mass transfer, transients and variables, and chemical evolution/the origin of the elements.

At Columbia, I’m working with Melissa Ness to investigate the origins of barium-rich stars with MESA and the GALAH spectroscopic survey. I am also a visiting scientist at the American Museum of Natural History, where I’m working with Michael Shara on constraining the intergalactic populations of the Local Group with the Condor Array Telescope.

In June 2023, I graduated from the University of Chicago with a B.S. in astrophysics and a minor in English and creative writing. My undergraduate research covered a wide range of topics, from pre-main-sequence binary stars to integrated spectroscopy of distant elliptical galaxies.

When I’m not doing research, you can find me writing for Astrobites, helping run Columbia Astronomy outreach events, or reading/writing science fiction (recommendations always welcome)!
