Summary

 

Summary

My research in High Energy Particle Physics revolves around searching for Physics beyond the Standard Model through precision measurements of the recently discovered Higgs boson. 

I have been a member of the CMS Collaboration since 2010, and have worked on measuring the properties of the Higgs boson, and searches for exotic Higgs boson decay modes including decays to Dark Matter particles.  

More recently, I have been active in the development and use of sophisticated statistical methods, including the use of machine-learning based methods, to (re-)interpret Higgs boson measurements and searches, and preserve the results for the future. 

I teach a post-graduate course on Statistics for High Energy Physicists within the Imperial HEP group
