About Me

Postdoctoral Fellow in Astronomy

Hi there! My name is Adina Feinstein. I am a NASA Sagan NHFP Fellow in the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder.

I consider myself to be a fairly broad observer. I've used observations from the far-Ultraviolet to the Infrared to understand stellar activity from young stars and planetary atmospheric compositions. I've used a slew of ground-based telescopes and space-based observatories to answer my scientific questions of interest.

I received my bachelor's degree from Tufts University in Boston. My undergraduate thesis focused on identifying and characterizing lensed galaxies in the Hubble Frontier Fields images. I am originally from New York, which means no matter how long I've lived in Chicago, I'll never believe deep dish pizza is pizza.
