Matt Belhorn is an HPC support specialist, providing technical support and training to researchers employing the OLCF’s leadership-class public research compute resources.

Matt has a research background in experimental high-energy particle physics. He was a long-time collaborator of the Belle and BelleII CP-violation experiments located at the Japanese High-Energy Accelerator Research Organization (KEK). His research efforts include contributions to the design and construction of BelleII’s Imaging Time-of-Propagation (iTOP) counter. The iTOP module measures the speed of relativistic subatomic charged particles and is a critical component of the whole detector which allows for particle identification and event reconstruction.

Matt developed his interest in high-performance computing while analyzing the physics of spontaneous particle-antiparticle oscillations.
