I am a postdoctoral fellow affiliated with the Kavli Institute for Cosmological Physics at the University of Chicago and the Department of Physics at the University of Michigan. I am interested in techniques in experimental laser interferometry and their application to measurements of classical and quantum gravity. I currently work with Professors Stephan Meyer and Craig Hogan on the Fermilab Holometer, a high-power 40m laser interferometry experiment designed to explore the nature of space-time at small scales with unprecedented precision.

Our understanding of physics breaks down on distances smaller than 10-35 meters or over time intervals shorter than 10-44 seconds. At this threshold, known as the Planck scale, gravitational and quantum physics collide. The Holometer is searching for evidence of a new type of quantum position uncertainty originating from this scale, whose existence would imply a fundamental limit on the information content of space-time. No experiment to date would have been sensitive to this faint "blurring" of reality. A detection would open an experimental pathway toward understanding Planck-scale unification and quantum gravity.
