What I will be working on:

I am currently working on a search for b-jet resonances. This interesting signature has not been studied directly at a hadron collider since Run I of the Tevatron and is sensitive to a host of new phenomena, including Z-primes and axigluons. I am also deeply involved in the study of a wide variety of exotic signatures, as co-convener of the exotica non-resonance subgroup at CMS. In my spare time, I develop software tools for physicists to evaluate the statistical sensitivity of their analyses. Ultimately, I plan to become involved in studying boosted Higgs decays to b-bbar, both as a signature for discovery and as an object for the discovery of new physics beyond the standard model.

My role in CMS past and present:

As a member of CMS for the past two and a half years, I performed the most sensitive search at a particle collider for large extra dimensions in the diphoton final state. This paper, recently submitted to JHEP, extends lower limits on the fundamental Planck scale to 1.6--2.3 TeV depending on the number of extra dimensions. I have also been engaged in the commissioning of the HCAL subdetector for data taking. I wrote software algorithms to identify and reject anomalous electronics noise present in the barrel and endcap hadronic calorimeter.
