Biographical Sketch:
Professor Tipton is the Eugene Higgins Professor of Physics at Yale University. He was Chair of the Physics Department at Yale from 2013-2019. Prior to joining the faculty at Yale (2006), he was an Assistant, Associate, and full Professor at the University of Rochester. Before Rochester, Tipton was the Wilson Fellow at Fermi National Accelerator Laboratory as well as a postdoctoral Fellow at Lawrence Berkeley Laboratory.
Tipton was co-convener of the Collider Detector at Fermilab (CDF) Top and B Quark Physics Group, a member of the Physics Advisory Committee at Fermilab, and a member of the Editorial and Planning Committee for the journal Annual Review of Nuclear and Particle Science. He served as Chair of the Yale Department of Physics from 2013-2019.
Research:
Prof. Tipton’s research group is conducting research as part of the ATLAS experiment which collects data from proton-proton collisions at the LHC located at CERN in Geneva Switzerland. They have two main areas of research.
First, in collaboration with Prof. Sarah Demers’ group, the Tipton group is taking the lead in a measurement of the quantum numbers of the newly discovered Higgs boson. By studying the decay angular correlations of the Higgs decay to pairs of tau leptons, the researchers will be sensitive to the charge conjugation and parity properties of the Higgs coupling to the tau. This work will be an extension of a previous ATLAS publication, for which Tipton hopes to use the group’s expertise in deep neural networks to gain sensitivity.
Secondly, in Yale’s Wright Lab, the group is helping to construct an upgrade to the ATLAS particle tracking system. Planned upgrades to the LHC accelerator will open exciting new physics opportunities. These upgrades will necessitate more collisions per beam crossing, which will require a new ATLAS tracker that is more radiation hard and has better spatial resolution.
In clean room facilities at Wright Lab, the Tipton group is fabricating the support structures call stave cores. Each stave core will have 28 thin silicon-wafer strip particle detectors mounted on it. Staves will reside in the central (barrel) region of the new tracker. Stave cores are fabricated with advanced composite materials such as carbon foam. The group is using robotic technology and thermal imaging for tests of parts and completed stave cores.

Honors & Awards:
Prof. Tipton is a Fellow of the American Physical Society. He received a National Science Foundation Young Investigator Award (1992—97), an Outstanding Junior Investigator Award from the U.S. Department of Energy (1991—1996), as well as the University of Rochester Department of Physics and Astronomy Annual Award for Excellence in Teaching (1995). Tipton was selected Teacher of the Year, Honorable Mention, by the University of Rochester Student’s Association, in 1994.
