Chang Liu Telephone: 765-494-5987 Office: Physics 377 Chang Liu is finishing his Ph.D. in experimental particle physics at the Department of Physics of Purdue University. He has been working within the collaboration of Compact Muon Solenoid experiment. The particle detector is one of the two general purpose detectors on the world’s largest machine, the Large Hadron Collider, near Geneva, Switzerland. He worked on the implementation of the tracking algorithms in the muon offline reconstruction and high level trigger system integrated in the CMS software. Besides that, he is studying physics of cosmic rays, phenomena of electroweak physics and new physics models resulting in final states with two muons. Before coming to Purdue, Chang spent his first fifteen years in his hometown on the side of Honghu lake and Yangtze river, and then went to college at University of Science and Technology of China. Besides wide interest in programming and physics, he also enjoys table tennis, go and reading.
