Biography/Details

Ben earned his Ph.D. in physics from Carnegie Mellon in 2015. He then worked as a postdoctoral researcher at the University of Pittsburgh until 2021, when he joined the �Ļ�ӰԺ faculty. His area of research is experimental high energy physics, and he works on the experiment in Geneva Switzerland. In particular, he looks for hints of new particles in decays of the Higgs boson. Ben also works on the ATLAS trigger system, which determines which collisions should be saved in a fraction of a second. He was awarded an grant in 2022, which he uses to support student contributions to the ATLAS experiment.
