Hi, I'm Andy Casey!

I'm an astrophysicist at Monash University (Melbourne, Australia).

I research stars: I want to know what they're made of, how they change with time, and how useful are they as tracers for understanding how our galaxy (and others) have formed.

I have worked on stars that should not exist, stars that should exist but we haven't found any, and every kind of normal star in between.

I contribute to large spectroscopic surveys. I am head of data analysis for Milky Way Mapper, one of the three mappers for the Sloan Digital Sky Survey.
