Andre David Tinoco Mendes (EP/CMX)
André is presently focused on the upgrade of the CMS endcap calorimeter for the HL-LHC phase, starting in the mid 2020s. The new calorimeter is a highly-granular silicon detector presenting multiple challenges.
Between 2015 and 2017, André co-convened the CMS Higgs Physics Analysis group. He used the CERN hostel for the first time in the year 2000 just before he decided to embark on a PhD in the NA60 fixed-target experiment. He worked on the silicon pixel and microstrip detectors of NA60 and his analysis of intermediate mass dimuon events paved the way for the discovery of thermal radiation shining off a QGP in heavy-ion collisions.
In 2006, André joined the CMS experiment where he led the commissioning of the ECAL. With the first LHC collision data, he went to perform the first LHC cross-section measurement of isolated single photon production.
Since 2010 that André was heavily involved in the search for - and later observation of - the Higgs boson in the diphoton decay channel. André's need to understand the big picture led him to become one of the conveners of the CMS Higgs Combination and Properties group, as well as CMS contact in the LHC Higgs Cross Section Working Group for exploring the properties of this new particle. Before the LHC Run 2, André was a major contributor to the CMS combination of Run 1 Higgs results, and was deeply involved in combinations between ATLAS and CMS, such as the LHC combined measurement of the Higgs boson mass, which is the scientific article with the largest ever number of co-authors.
André's interests include science communication and the usefulness of CERN for non-particle physicists in general. That is why he is a CERN official guide since 2004 and was involved with the CLOUD experiment for six years.
