Gage DeZoort Princeton ORFE / Physics

Welcome! I'm a postdoctoral researcher building efficient, scalable machine learning algorithms for scientific measurements. Right now I'm focused on numerically stable graph neural networks tuned for hyperparameter transfer—models that agree on a single learning rate—so they can power tasks like stellar stream identification in large sky surveys and jet tagging in collider datasets.

About

I grew up in Tuscaloosa, Alabama, where in my senior year of high school I developed a deep interest in physics and astronomy through pop-sci offerings like Neil deGrasse Tyson's Cosmos and Brian Greene's The Elegant Universe. I completed my undergraduate studies at the University of Virginia, double majoring in Physics and Engineering Science. While there, I worked with Prof. Craig Group building cosmic ray veto panels for the Mu2e experiment, and with Prof. Chris Neu on projects tied to the CERN Compact Muon Solenoid (CMS) detector.

I continued my CMS work as a PhD student under Prof. Dan Marlow at Princeton University, culminating in a dissertation focused on a search for a pseudoscalar Higgs boson decaying to Zh with ℓℓ + ττ final states. During my PhD years I developed a strong interest in machine learning, particularly charged particle track reconstruction via graph neural networks. That led to collaborations with Boris Hanin, where we characterized and alleviated numerical issues like poor initialization, oversmoothing, and correlation collapse in graph neural networks (GNNs).

My postdoc is focused on furthering the study of numerically stable GNNs—especially graph transformers—by tuning them for hyperparameter transfer: models are parametrized so they all agree on the same learning rate. I'm now working on several scientific applications for these models, including stellar stream identification in large astronomical surveys and jet tagging in collider datasets.

Creative side quests

Outside of academia, I'm an avid progressive metal guitarist, writing and recording music with several bands. You can explore recent riffs, performances, and works-in-progress on my music profile.
