I am curious about what our world is made of at the smallest, most fundamental level. I am a particle physicist, exploring the energy frontier, studying the laws of nature at the highest energies together with my [MSU colleagues]( and collaborators from around the world on the [ATLAS experiment]( at [CERN]( near Geneva, Switzerland.

The CERN LHC is a proton-proton collider that is expected to discover new particles and reveal physics at the electroweak symmetry breaking scale. [ATLAS]( and [CM]( found the Higgs boson in 2012 and will continue to accumulate data at increasing collision energies. I am excited for the breakthroughs in the understanding of our world that should emerge. I work in the [top group]( on single top quark production and in the [exotics group]( on Z' searches in the dilepton final state.

Together with a team of very talented MSU students, we have produced a [planetarium show on the LHC and ATLAS](, running at the [Abrams planetarium]( at MSU and possibly coming to a planetarium near you.

I have been on the [DØ]( experiment at the [Tevatron]( proton-antiproton collider at [Fermilab]( near Chicago, Illinois since 2000. I was co-convener of the analysis group that [discovered single-top quark production]( You can read about the many subjects that I have investigated on my [DØ home page](
