超環面儀器
Trained in theoretical physics, his primary activity is with the ATLAS experiment at CERN's Large Hadron Collider, which he joined in 1996; he served as ATLAS physics coordinator in 2006–2007 and currently heads Berkeley Lab's ATLAS group. His research emphasizes the importance of experiment in testing theoretical ideas, and in driving theoretical developments aimed at understanding interactions among fundamental particles. Much of his research looks to show how the Standard Model can be tested at hadron colliders.
