Dr. Kirill Prokofiev received his Master of Science degree in physics from St Petersburg State Polytechnical University in 2001. He received his PhD in Elementary Particle Physics from the University of Zürich in 2006. Dr. Prokofiev held research appointments at the University of Sheffield and New York University as well as Fellowships at CERN and INFN.

For several years Dr. Prokofiev worked in CMS and ATLAS experiments at the Large Hadron Collider at CERN. He made a major contribution to the preparation of data reconstruction and analysis of these experiments. In 2012-2013 he participated in the analyses resulted in the discovery of the Higgs boson by the ATLAS experiment at the LHC. In 2013-2014 he played a leading role in establishing the quantum numbers of the Higgs boson using ATLAS data. For years 2014-2015 Dr. Prokofiev was appointed as coordinator of ATLAS Higgs combination and properties subgroup. His current physics interests are concentrated around the experimental measurements of Higgs properties, searches for heavy Higgs particles and searches for the Physics Beyond the Standard Model.
