Sagar Vidya Addepalli

Particle Physicist

I am a Research Associate at SLAC / Stanford University, working on the ATLAS experiment at CERN's Large Hadron Collider.

My current focus is on searches for long-lived particles and on real-time machine learning for collider trigger systems — including GELATO, the first anomaly-detection trigger chain deployed in ATLAS. Previously I led measurements in the Higgs sector and contributed to the ATLAS silicon inner tracker construction.

I am also a member of the A3D3 Institute, working at the intersection of accelerated AI and fundamental physics.
