About Me

I am currently a postdoc in Carnegie Mellon University’s High Energy Theory group. I have formerly held affiliations with Cambridge (twice), Utrecht, Amsterdam, and Penn.

Contact me at ggoon@andrew.cmu.edu.


I study the applications of quantum mechanics to gravitational systems. I am particularly focused on Effective Field Theory methods.

Themes found in my work are:

  • Early Universe Physics: What signatures of primordial physics are cosmologically observable?
  • The Dark Sector: What is the nature of dark energy? Can cosmic acceleration by explained by any consistent long-distance modification of gravity?
  • Black Hole Physics: What can black holes tell us about high-energy physics?
