| Searches for New Physics at the LHC are described in the framework of a statistical test. Making a discovery corresponds to rejecting the hypothesis that the data are consistent with known background processes, and in addition one uses the data to test various signal models and to place limits on their parameters. Recent developments for carrying out these tests will be described, including methods for incorporating systematic uncertainties into a measure of experimental sensitivity and use of weighted Monte Carlo events.

| Prof. Cowan got his B.S. from University of California, Los Angeles in 1981, and Ph.D from University of California, Berkeley in 1988. He started his first postdoc position at Max-Planck-Institute Munich, then CERN and university of Siegen, Germany. In 1998, he started to work in Physics Department, Royal Holloway, University of London, with the positions through lecturer, senior lecturer, reader and professor. He has been working in different particle physics experiments: ALEPH (convener of the LEP2 QCD group), BaBar (PI in Royal Holloway), and ATLAS (convener of Statistics Forum).
His current research interests are focused on developing statistical analysis methods for analysis of particle physics data. He is frequently invited to give lectures on statistical data analysis around the world.
