A physicist at the Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL), Lajoie has shaped his career around finding hard-to-solve problems and coming up with new ways to tackle them.
Detectors are how physicists make the invisible visible. They capture signals produced in high-energy collisions, revealing essential features and behaviors that help us study the tiniest of quantum particles. Without detectors, even the most powerful accelerator cannot answer fundamental questions about matter. Detectors are the essential tools that turn collisions into insight and possibility into discovery.
