Research

My research is focused on the search for new phenomena in proton-proton collisions at the LHC accelerator using the ATLAS detector. Together with students and post-docs, I am currently investigating unusual decay of Higgs bosons and the prossible production of quantum black holes.

I have a special interest ATLAS trigger. During the 2011 LHC run, the proton beams were sufficiently intense to produce 400 million collisions per second. The job of the trigger is to select a few hundred events per second that are saved for further analysis. In the future we expect as many 4 billion collisions per second making the task of the triggering even more difficult.

I also have an ongoing interest in detector development for future energy frontier accelerators, such as a linear collider (LC).
